Kyrsten Lea Sinema (/ˈkɪərstən ˈsɪnəmə/ KEER-stən SIN-ə-mə; born July 12, 1976) is an American politician and former social worker serving as the senior United States senator from Arizona, a seat she has held since 2019. A former member of the Democratic Party, Sinema became an independent in December 2022.
Sinema was born in Tucson, Arizona, on July 12, 1976, to Marilyn (Wiley) and Dan Sinema. Sinema has an older brother and younger sister. Her father was an attorney. Her parents divorced when she was a child, and her mother, who had custody of the children, remarried. With her siblings, mother, and stepfather, Sinema moved to DeFuniak Springs, Florida, a small town in the Panhandle.
Sinema was raised as a member of the Church of Jesus Christ of Latter-day Saints (LDS Church). She graduated as valedictorian from Walton High School in DeFuniak Springs at age 16 and earned her B.A. from Brigham Young University (BYU) in 1995 at age 18. She left the LDS Church after graduating from BYU. Sinema returned to Arizona in 1995.
While employed as a social worker, Sinema completed a Master of Social Work degree at Arizona State University in 1999. In 2004, she earned a J.D. degree from Arizona State University College of Law and started working as a criminal defense lawyer. In 2012, she earned a Ph.D. in justice studies from Arizona State and in 2018, she completed an online M.B.A. from the W. P. Carey School of Business.
In 2000, Sinema worked on Ralph Nader's presidential campaign. In 2001 and 2002, she ran for local elected offices as an independent and lost. In 2002, The Arizona Republic published a letter from Sinema criticizing capitalism. She wrote: "Until the average American realizes that capitalism damages her livelihood while augmenting the livelihoods of the wealthy, the Almighty Dollar will continue to rule." In 2003, she protested Joe Lieberman's unsuccessful 2004 presidential bid, telling the Hartford Courant: "He's a shame to Democrats. I don't even know why he's running. He seems to want to get Republicans voting for him – what kind of strategy is that?"
In 2005 and 2006, she co-hosted an Air America radio show with 9/11 truther Jeff Farias. In 2006, Sinema said she opposed "war in all its forms", and wrote: "As one of the core organizers against the war from day one (September 12, 2001), I have always and will always continue to oppose war in all its forms."
In 2002, Sinema first ran for the Arizona House of Representatives as an independent affiliated with the Arizona Green Party. She finished in last place in a five-candidate field, receiving 8 percent of the vote.
In 2003, Sinema became an adjunct professor teaching master's-level policy and grant-writing classes at Arizona State University School of Social Work and an adjunct business law professor at Arizona Summit Law School, formerly known as Phoenix School of Law. Sinema began her political career in the Arizona Green Party before joining the Arizona Democratic Party in 2004, and called herself a "Prada socialist".
As an antiwar activist in the years after 9/11, Sinema "led a group that distributed flyers depicting an American soldier as a skeleton inflicting 'U.S. terror' in Iraq and the Middle East." The flyers "promoted a February 2003 rally organized by Local to Global Justice, an anti-war group Sinema co-founded". Sinema was described in news reports as an organizer and sponsor of the rally and was listed as the point of contact for the event. One flyer referred to "Bush and his fascist, imperialist war", saying, "Government is slavery", and describing laws as "cobwebs for the rich and chains of steel for the poor". CNN said that such positions were "a contrast from the more moderate profile she has developed since her 2012 election to Congress".
While in the Green Party, Sinema was its local spokesperson, working to repeal the death penalty and organizing antiwar protests. She had organized 15 antiwar rallies by the time the Iraq War began. She also opposed the war in Afghanistan. During a February 15, 2003, protest in Patriots Square Park in Phoenix, a group led by Sinema distributed flyers portraying a U.S. service member as a skeleton "inflicting 'U.S. terror' in Iraq and the Middle East".
Sinema joined the Democratic Party in 2004. That year, Sinema and David Lujan won the two seats for Arizona's 15th district, with 37 percent of the vote for Sinema and 34 percent for Lujan over incumbent representative Wally Straughn. Sinema was reelected three times with over 30 percent of the vote. In 2008, Sinema completed the Harvard University John F. Kennedy School of Government program for senior executives in state and local government as a David Bohnett LGBTQ Victory Institute Leadership Fellow. In 2009 and 2010, Sinema was an assistant Minority Leader for the Democratic Caucus of the Arizona House of Representatives.
Sinema served three terms as a state representative for the 15th legislative district from 2005 to 2011, one term as the state senator for the 15th legislative district from 2011 to 2012, and three terms as the United States representative for the 9th district from 2013 to 2019. She began her political career in the Arizona Green Party and rose to prominence for her progressive advocacy, supporting causes such as LGBT rights and opposing the war on terror. She left the Green Party to join the Arizona Democratic Party in 2004 and was elected to a seat in the United States House of Representatives in 2012. After her election, she joined the New Democrat Coalition, the Blue Dog Coalition and the bipartisan Problem Solvers Caucus, amassing one of the most conservative voting records in the Democratic caucus. Sinema won the 2018 Senate election to replace the retiring Jeff Flake, defeating Republican nominee Martha McSally. She is the first bisexual and the second openly LGBT woman (after Tammy Baldwin) to be elected to Congress, in the House of Representatives in 2012 and in the Senate in 2018. She is also the first woman elected to the Senate from Arizona and the only religiously unaffiliated member of the US Senate.
According to Elle, "her first public comment as an elected official came in 2005, after a Republican colleague's speech insulted LGBT people. 'We're simply people like everyone else who want and deserve respect', she passionately declared. Later, when reporters asked about her use of the first person, Sinema replied, 'Duh, I'm bisexual.'" In 2012, when running for U.S. House, Sinema said she did not remember disclosing her sexual orientation in 2005 and declined to discuss the significance of being the first openly bisexual member of the House.
According to a profile in The Advocate, "Sinema has her sights set on advancing LGBT rights." She has a history of policy advocacy regarding LGBT rights and issues. In 2006, Sinema was among the leading opponents of a proposed amendment to the Arizona state constitution which would have banned same-sex marriages and civil unions. The proposal failed in Arizona, the first time that a state rejected a ban on same-sex marriage, but a second proposed amendment banning only same-sex marriage passed in 2008 with Sinema in opposition again. She supports same-sex marriage, domestic partnership recognition, and adding gender identity to anti-discrimination laws.
In 2006, Sinema told a radio host that she was "the most liberal member of the Arizona State Legislature". Also in 2006, she sponsored a bill urging the adoption of the DREAM Act, and co-chaired Arizona Together, the statewide campaign that defeated Proposition 107, which would have banned the recognition of same-sex marriage and civil unions in Arizona. In 2008, a similar referendum, Proposition 102, passed.
In 2006, Sinema was asked about "new feminism", and responded: "These women who act like staying at home, leeching off their husbands or boyfriends, and just cashing the checks is some sort of feminism because they're choosing to live that life. That's bullshit. I mean, what the fuck are we really talking about here?" After facing criticism, Sinema apologized and said the interview format was intended to be a "lighthearted spoof", adding: "I was raised by a stay-at-home mom. So she did a pretty good job with me."
According to The Arizona Republic, while serving in the Arizona State Legislature, she introduced more bills regarding the death penalty than bills regarding military or veterans' families. In 2007, she introduced HB 2278, which would require the Arizona Supreme Court to "strike" any prior death sentence and "enter in its place a sentence of natural life", as in life without parole.
Sinema campaigned against Proposition 107, a referendum to ban the recognition of same-sex marriage and civil unions in Arizona. In 2008, she led the campaign against Proposition 102, another referendum that would have banned the recognition of same-sex marriage in Arizona. Proposition 102 was approved with 56% of the vote in the general election on November 4, 2008. Sinema chaired a coalition called Protect Arizona's Freedom, which defeated Ward Connerly's goal to place an initiative on the state ballot that would eliminate racial-preference programs.
In June 2009, Sinema was one of 32 state legislators appointed by President Barack Obama to the White House Health Reform Task Force, which helped shape the Affordable Care Act. "Thanks in part to her hard work in improving the bill", she was invited to attend the Obamacare bill signing at the White House in March 2010.
In 2010, Sinema sponsored a bill to give in-state tuition to veterans; it was held in committee and did not receive a vote. Also in 2010, Sinema was named one of Time magazine's "40 Under 40". The Center for Inquiry gave Sinema its Award for the Advancement of Science and Reason in Public Policy in 2011.
In 2010, Sinema was elected to the Arizona Senate, defeating Republican Bob Thomas, 63 to 37 percent.
In June 2011, Sinema said she was considering running for the U.S. House of Representatives in 2012. She lived in the same Phoenix neighborhood as incumbent Democratic congressman Ed Pastor, but was adamant that she would not challenge another Democrat in a primary. On January 3, 2012, Sinema announced her bid for Congress, in the 9th congressional district. The district had previously been the 5th, represented by freshman Republican David Schweikert; it contained 60 percent of the old 5th's territory. Schweikert had been drawn into the 6th district—the old 3rd district—and sought reelection there.
According to Roll Call, Sinema considered herself bipartisan. It was drawn as a "fair-fight" district, and President Barack Obama won the district by four points in 2012. In September 2014, she was endorsed for reelection by the U.S. Chamber of Commerce, becoming one of five Democrats to be endorsed by the Chamber in the 2014 congressional election cycle. She was reelected with approximately 55 percent of the vote, beating Rogers by 13 points.
After joining Congress in 2012, she said her views on military force had "evolved", and that "you should never take military intervention off the table. When you do so, you give an out to a rogue nation or rogue actors." Lederman reported that "she said she favors aggressive diplomacy, crippling sanctions to combat proliferation, and swift, multilateral intervention as a last resort". Since joining Congress, she has voted against the Iran Nuclear Deal and supported Trump's missile attack on Syria.
Although Sinema was not required to resign her State Senate seat under Arizona's resign-to-run laws (since she was in the final year of her term), she did so on the same day that she announced her candidacy. On August 28, 2012, Sinema won the three-way Democratic primary with nearly 42 percent of the vote. Her opponents, state Senator David Schapira and former Arizona Democratic Party chairman Andrei Cherny, a former speechwriter in the Clinton administration, each finished with less than 30 percent of the vote.
In 2013, Sinema co-sponsored Rep. Sean Patrick Maloney's letter, which opposed Saudi Arabia for "the use of torture and capital punishment against the LGBTQ community".
In June 2013, Sinema became one of 29 original cosponsors of the bipartisan LIBERT-E (Limiting Internet and Blanket Electronic Review of Telecommunications and Email) Act, along with Representative Justin Amash. The legislation would limit the National Security Agency (NSA) to only collecting electronic information from subjects of an investigation.
In July 2013, Sinema joined a bipartisan majority and voted against an amendment to a defense appropriations bill (offered by Amash) to prohibit the NSA from monitoring and recording details of U.S. citizens' telecommunications without a warrant.
On November 17, 2013, Sinema completed an Ironman Triathlon in a little over 15 hours. She was the second active member of Congress, after Senator Jeff Merkley, to finish a long-distance triathlon, and the first to complete an Ironman-branded race. She completed the 2015 Ironman World Championship in Kona, Hawaii.
On December 25, 2013, Sinema climbed to the summit of Mount Kilimanjaro.
Sinema favors gun control measures such as requiring background checks on gun sales between private citizens at gun shows, and requiring a license for gun possession. In 2014 and 2018 the NRA Political Victory Fund (NRA-PVF), which opposes gun regulations, gave Sinema a "D" rating. Gun Owners of America gave her a 17% rating.
Sinema ran for reelection in 2014 and was unopposed in the Democratic primary, which took place on August 26, 2014. She faced Republican Wendy Rogers in the general election.
Sinema voted against repealing the Affordable Care Act, but has called for reforms to the law. In a 2012 congressional campaign debate, she said the health care law was not perfect, and that in Congress she would work to amend it to make it work effectively. Sinema voted to delay the imposition of fines on those who did not purchase insurance in 2014. She also voted to repeal the Medical Device Tax and for the Keep Your Health Plan Act of 2013.
The Federation for American Immigration Reform, a PAC that seeks to limit both legal and illegal immigration, gave Sinema a 33% rating in 2018, and UnidosUS, which supports a pathway to citizenship for undocumented immigrants, gave Sinema a score of 88% in 2014.
In 2015, Sinema was one of just seven House Democrats to vote in favor of a Republican-backed bill to repeal the estate tax, which affects about 0.2% of Americans in the U.S. each year (estates of $5.43 million or more for individuals, or $10.86 million or more for couples). That same year, she voted to change the Consumer Financial Protection Bureau's leadership from a single director to a bipartisan commission.
In the House of Representatives, Sinema was a member of the Blue Dog Coalition and the Problem Solvers Caucus. According to the Bipartisan Index created by the Lugar Center and the McCourt School of Public Policy, Sinema was the sixth most bipartisan member of the U.S. House of Representatives during the first session of the 115th United States Congress. The National Journal's 2013 vote ratings placed Sinema near the center of their liberal–conservative scale. In 2015, she voted with the majority of her party 73% of the time. In 2015 and 2016, Sinema did not vote for Nancy Pelosi for speaker of the U.S. House. In 2016, the National Journal gave her a composite ideology score of 57% liberal and 43% conservative. She was one of the most conservative House Democrats during her House tenure.
Sinema supports the use of military force to stop genocide, such as in Sudan, Somalia and Rwanda. She wrote a doctoral dissertation on the 1994 Rwandan genocide that Lexington Books published in 2015 under the title Who Must Die in Rwanda's Genocide?: The State of Exception Realized.
In 2016, Sinema was one of five House Democrats to vote for a Republican-backed bill barring the Federal Communications Commission (FCC) from regulating broadband rates. Her vote broke from her party; other Democrats were strongly opposed to the measure, and President Obama said he would veto it if it passed.
In 2016, with Republican representative John Katko of New York, Sinema cosponsored the Working Parents Flexibility Act (H.R. 4699). This legislation would establish a tax-free "parental savings account" in which employers and parents could invest savings tax-free, with unused funds eligible to be "rolled into qualifying retirement, college savings or ABLE accounts for people with disabilities without tax penalties". In September 2018, she voted "to make individual tax cuts passed by the GOP [in 2017] permanent". She was one of three Democrats to break with her party and vote for the tax cuts being made permanent.
In 2017, Sinema and 47 other House Democrats voted with the majority of House Republicans on H.R. 115, Thin Blue Line Act of 2017, which was opposed by the ACLU. The bill would "expand the list of statutory aggravating factors in death penalty determinations" to include the killing or targeting of a law enforcement officer, first responder, or firefighter.
In March 2018, Sinema donated to charity $33,800 in campaign contributions she had received from Ed Buck, a prominent Democratic donor who came under scrutiny after a homeless escort died of a drug overdose at his California home in 2017. She had previously donated to charity $53,400 in campaign contributions from people with ties to Backpage, a website that was seized by the United States Department of Justice after it was accused of knowingly accepting ads for sex with underage girls.
On February 12, 2021, Sinema became the second Democratic senator after Joe Manchin to announce her opposition to including a $15/hour minimum wage as part of a COVID-19 relief bill. On March 5, 2021, Sinema voted against an increase of the federal minimum wage to $15 an hour, proposed by Senator Bernie Sanders as part of the American Rescue Plan Act of 2021. She did so by flashing a thumbs-down, and some commentators compared her demeanor to that of former Arizona senator John McCain, who had voted with a dramatic thumbs-down gesture in 2017; others compared her to former French queen Marie Antoinette, to whom the phrase "let them eat cake" is attributed. Sinema's office responded that any commentary on her clothes and demeanor was sexist. Her vote was at odds with that of fellow Democrat Mark Kelly, the junior Arizona senator, who supports a $15/hour minimum wage.
On September 28, 2017, Sinema officially announced her candidacy for the Class I United States Senate seat held by Republican incumbent Jeff Flake, who declined to seek reelection the next month.
When asked about Roe v. Wade in 2018, Sinema said the ruling should not be overturned and that she supports a woman's right to have an abortion. In 2020, she had a 100% rating from the abortion-rights organization Planned Parenthood, and a 0% rating from the anti-abortion organization Campaign for Working Families. She was endorsed by EMILY's List, an abortion-rights-focused political action committee, until 2022, when she voted with Republicans against changing the filibuster to allow passage of the Freedom to Vote and John R. Lewis Voting Rights Act. That vote also cost her the support of the abortion-rights advocacy group NARAL Pro-Choice America. After Roe v. Wade was overturned in June 2022, Sinema said the decision "endangers the health and well-being of women in Arizona and across America."
Federal Election Commission filings released in April 2018 showed Sinema had raised over $8.2 million, more than the three leading Republican primary contenders combined.
Sinema opposed Arizona SB 1070. She has argued that mass deportation of undocumented immigrants is not an option and supported the DREAM Act. Her 2012 campaign website stated that "we need to create a tough but fair path to citizenship for undocumented workers that requires them to get right with the law by paying back taxes, paying a fine and learning English as a condition of gaining citizenship." In July 2018, she broke with her party by voting with Republicans against abolishing ICE.
Journalist Jonathan Martin wrote in The New York Times in September 2018 that Sinema was running "one of the most moderate-sounding and cautious Senate campaigns this year, keeping the media at arms-length and avoiding controversial issues", and said her campaign was generally reluctant to bring up President Donald Trump. According to Martin, both Republicans and Democrats said that Sinema had "few major legislative accomplishments to her record" and was running "on a political image that she has shaped and reshaped over the years. And nothing is more central to it now than her childhood homelessness."
In 2019, Sinema was one of four Democratic-caucusing senators to join all Republicans in voting against the Green New Deal, a stimulus program that aims to address climate change and economic inequality, while most other Democrats voted "present". In April 2019, Sinema was one of three Democrats who voted with Republicans to confirm David Bernhardt, a former oil executive, as Secretary of the Interior Department.
In 2019, Sinema was the sole Senate Democrat not to co-sponsor the Save the Internet Act, which would restore Obama-era regulations preventing ISPs from throttling consumers' website traffic. She worked with Senate Republican Roger Wicker to develop their own net neutrality bill.
Sinema has completed numerous marathons. In 2019, she completed a marathon in 3:28:17, which was fast enough for her (female) age group to qualify for the Boston Marathon. Two weeks before her Boston-qualifying race, she ran a three-mile race in 20:42, setting a record for women in Congress. In 2020, she set a personal record of 3:21:45 and later in 2021, she broke her right foot while running a marathon, requiring her to use a hands-free crutch.
On November 12, many news sources called the U.S. Senate race for Sinema, and the Republican nominee, Martha McSally, conceded. Sinema was sworn in with the 116th United States Congress on January 3, 2019.
Sinema was sworn in as a member of the U.S. Senate on January 3, 2019. During the oath of office ceremony, led by Vice President Mike Pence, she decided to be sworn in not on the traditional Bible, but on copies of the United States Constitution and the Constitution of Arizona. She is the senior U.S. senator from Arizona; the junior U.S. senator for Arizona is Democrat Mark Kelly. Kelly defeated Sinema's 2018 general election opponent, Martha McSally, who was appointed to fill the Senate seat vacated upon the resignation of Jon Kyl, who had been appointed to fill the Senate seat vacated upon the death of John McCain.
In February 2019, Sinema was one of 20 senators to sponsor the Employer Participation in Repayment Act, enabling employers to contribute up to $5,250 to their employees' student loans.
On February 5, 2019, Sinema voted for a bill that would make improvements to certain defense and security assistance provisions, authorize the appropriation of funds to Israel, and reauthorize the United States-Jordan Defense Cooperation Act of 2015. On March 13, 2019, she voted to remove the United States Armed Forces from hostilities in the Republic of Yemen that have not been authorized by Congress.
On February 12, 2019, Sinema voted along with the whole Senate for the Natural Resources Management Act, which provides for the management of the natural resources of the United States.
On February 14, 2019, Sinema voted to confirm William Barr as attorney general.
On March 14, 2019, Sinema voted against Trump's National Emergency declaration on border security.
On July 30, 2019, Sinema and Senator Bill Cassidy released a proposal under which new parents would be authorized to advance their child tax credit benefits in order to receive a $5,000 cash benefit upon either birth or adoption of a child. The parents' child tax credit would then be reduced by $500 for each year of the following decade.
In 2021, Sinema opposed prescription drug pricing reform proposals in House and Senate versions of a Democrat-crafted spending bill. On October 8, 2021, Jacobin reported:
According to GovTrack, Sinema has a centrist to center-right voting record in the Senate, to the right of Republican Senators Susan Collins and Lisa Murkowski. According to FiveThirtyEight, as of January 2021, Sinema had voted in line with Donald Trump's position on legislation about 50% of the time. As a result, the Arizona Democratic Party suggested censuring her. But after delaying the vote and watering down the resolution from a censure to an advisement, the Party ultimately tabled the resolution.
Sinema urged Senate colleagues to vote in favor of the proposed January 6 commission to further investigate the storming of the United States Capitol on January 6, 2021. In a joint statement with Senator Joe Manchin, she said, "we implore our Senate Republican colleagues to work with us to find a path forward on a commission to examine the events of January 6th." Sinema was one of two Senate Democrats who did not vote on it, the other being Senator Patty Murray of Washington. Murray and Sinema both cited a "personal family matter" for their absence.
On January 25, 2021, a spokesperson for Sinema told The Washington Post that she is "against eliminating the filibuster" and "not open to changing her mind" on the issue. Additionally, Sinema has spoken out on the elimination of the judicial filibuster as a key reason for increased politicization of the judiciary.
On February 4, 2021, Sinema voted against providing COVID-19 pandemic financial support to undocumented immigrants.
In October 2021, five of the veterans Sinema had selected for her advisory council as liaisons to the Arizona service member community resigned. Their resignation letter accused her of "answering to big donors rather than your own people" and criticized her opposition to key Democratic Party issues, such as abolishing the filibuster and aspects of Biden's Build Back Better Plan.
Sinema and Senator Joe Manchin met with President Biden the same day to discuss their concerns with the bills. Observers have noted that Sinema is one of the largest beneficiaries of pharmaceutical political action committee money in Congress, and has been described as a "Pharma Favorite". KHN reported: "For the 2019–20 election cycle through March, political action committees run by employees of drug companies and their trade groups gave her $98,500 in campaign funds, Kaiser Health News' Pharma Cash to Congress database shows. That stands out in a Congress in which a third of the members got no pharma cash for the period and half of those who did got $10,000 or less." Sinema's haul was "twice that of Sen. Susan Collins of Maine, considered one of the most vulnerable Republicans in November, and approached that of fellow Democrat Steny Hoyer, the powerful House majority leader from Maryland." Senator Bernie Sanders indirectly called her out, saying: "Take a hard look at those people who are opposed to strong legislation to lower the cost of prescription drugs, and take a look at their campaign-finance reports. See where they get their money, how many of them get their money from the pharmaceutical industry, and the executives there. And I think there will be a direct correlation." On October 18, 2021, Politico reported:
In 2022, Sinema voted for the Inflation Reduction Act, a major piece of climate and energy legislation designed to invest in renewable energy, which includes billions of dollars for drought relief.
In 2022, several provisions of the Inflation Reduction Act of 2022 were changed after negotiations with Sinema: a provision narrowing the carried interest loophole was dropped, a 1% excise tax on stock buybacks was added, and manufacturing exceptions were added to the corporate minimum tax.
In January 2022, Sinema and Democratic Senate colleague Joe Manchin voted against changing the Senate filibuster rule. The proposed rule change, which would have allowed certain voting rights bills to advance to the Senate floor without meeting the Senate's 60-vote threshold, was voted down by a 52-48 margin. Days later, the Arizona Democratic Party executive committee censured Sinema for voting to retain the filibuster rule.
On January 22, 2022, the Arizona Democratic Party executive board voted to censure Sinema for voting with Senate Republicans to maintain the filibuster, preventing passage of a voting rights bill.
According to FiveThirtyEight, as of July 2022, Sinema had voted with President Biden's position on legislative issues 94% of the time.
In December 2022, Sinema announced that she had left the Democratic Party and registered as an independent. She continued to caucus with the Democratic Party for committee assignments.
In December 2022, Sinema changed her party registration to Independent.
In December 2022, Sinema was a lead cosponsor and negotiator on the Respect for Marriage Act, which passed the Senate, 61–36.
Late in 2023, Sinema was brought in as the medium between progressive Democrat Chris Murphy of Connecticut and conservative Republican James Lankford of Oklahoma to negotiate a bill to handle the Mexico–United States border crisis. Days before the vote, pressure from Trump reduced Republican support from 20 senators to the four that voted in favor. Before the voting, Sinema admonished the defectors for playing "political theater" and said "the Senate has failed Arizona". On March 5, 2024, Sinema announced that she would retire from Congress at the end of her term and not seek reelection, saying that her approach to fostering compromise seemed to be "a model of the past".
Sinema was considered a key swing vote in the Senate, which was split 50–50 between Democrats and Republicans in the 117th U.S. Congress. She is one of three independents in the Senate, the others being Bernie Sanders and Angus King, both of whom also caucus with the Democrats. Sinema has announced she will not seek reelection in 2024.
