Diana DeGette

Diana Louise DeGette ( ; born July 29, 1957) is an American lawyer and politician serving as the U.S. representative for , which is based in Denver, since 1997. Previously, she served in the Colorado House of Representatives from 1993 to 1997. She is a member of the Democratic Party.

A progressive, DeGette was first elected to Congress in 1996. She served as Democratic chief deputy whip from 2005 to 2019, and has been the dean of Colorado's congressional delegation since 2007. In 2026, DeGette lost renomination in the Democratic primary to democratic socialist Melat Kiros.

Early life, education and career A fourth-generation Coloradan, DeGette was born in Tachikawa, Japan, the daughter of Patricia Anne (née Rose) and Richard Louis DeGette. Her parents were American, and at the time of her birth her father was serving in the armed forces. She graduated from Colorado College, where she earned a Bachelor of Arts degree in political science and was elected to the Pi Gamma Mu international honor society in 1979. She earned her Juris Doctor degree from the New York University School of Law in 1982. She then returned to Denver and began a law practice focusing on civil rights and employment litigation.

Colorado Legislature Long active in Denver politics, DeGette was elected to the Colorado House of Representatives in 1992. She was reelected in 1994 and chosen as assistant minority leader. She authored a law that guarantees Colorado women unobstructed access to abortion clinics and other medical care facilities, also known as the Bubble Bill. The United States Supreme Court found the Bubble Bill constitutional in Hill v. Colorado, 530 U.S. 703 (2000). DeGette also authored the state Voluntary Cleanup and Redevelopment Act, a model for similar cleanup programs.

Elections

1996 Longtime 1st district Representative Pat Schroeder chose not to run for a 13th term in 1996, prompting DeGette to run. Her principal opponent in the primary election was former City Council member Tim Sandos, whom Denver Mayor Wellington Webb endorsed shortly before the primary. DeGette won the primary with 55% of the vote, all but assuring her of election in the heavily Democratic district (the 1st has been in Democratic hands for all but four years since 1933). Schroeder, who stayed neutral during the primary, endorsed DeGette once DeGette became the nominee. DeGette won with 57% of the vote and has been reelected 14 times since, until losing renomination in 2026.

2026

DeGette ran for her sixteenth term in Congress in the 2026 United States House of Representatives elections for Colorado's 1st congressional district. DeGette faced two main primary challengers during the race, former corporate attorney Melat Kiros and University of Colorado Board of Regents member Wanda James.

DeGette was seen as vulnerable to a successful primary challenge due to her long tenure and changing demographics within her district. Despite identifying as a progressive, DeGette attracted criticism for accepting donations from Super PACs — seen as antithetical to progressivism — as well as her support of Israel and dismissiveness of the Gaza genocide. The latter issue particularly contrasted her with Kiros, who gained noteriety after being fired by her law firm for defending the rights of pro-Palestinian protestors. While defending her acceptance of donations from Super PACs, DeGette attempted to focus on her long tenure and positions on Congressional committees.

The primary race attracted high levels of outside spending, including $1.3 million spending from Super PACs during the last two weeks of the election in support of DeGette. Kiros highlighted the spending as an ethical issue, claiming that DeGette became dependent on campaign donations from industries she regulates such as AI.

DeGette's acceptance of PAC donations and stance on the genocide alienated voters, exacerbating claims she did not accurately represent her constituents. She ultimately lost renomination in the primary, with Kiros defeating her by double digits.

Tenure DeGette serves as the co-chair of both the Congressional Diabetes Caucus and Pro-Choice Caucus, and she is Vice Chair of the LGBT Equality Caucus. With the Democrats' victory in the 2006 midterm elections, DeGette briefly considered running for House Majority Whip, but bowed out in favor of Jim Clyburn of South Carolina.

DeGette sat as speaker pro tempore and presided over the debate on December 18, 2019, the day United States House of Representatives voted on the first impeachment of President Donald Trump.

DeGette received national attention in 2005, when the House of Representatives passed legislation she cosponsored to lift President George W. Bush's limits on federal funding for embryonic stem cell research. DeGette, who had been working on the measure since 2001, enlisted the support of Representative Michael N. Castle (Republican from Delaware), who became DeGette's principal Republican cosponsor of the legislation. The DeGette-Castle bill passed the Senate on July 18, 2006. President Bush vetoed the bill the next day — his first veto.

In 2007, DeGette served as the House Democrats' designated whip on the bill reauthorizing the State Children's Health Insurance Program (HR 3162). Although President Bush announced his opposition to the legislation, the House passed the bill on August 1, 2007, by a vote of 225 to 204. The Senate adopted a different version of the legislation the next day.

DeGette was also a cosponsor for the Udall Amendment to the House Energy Bill, which the House approved by a vote of 220 to 190 on August 4, 2007. The Amendment creates a national Renewable Energy Standard that requires electric suppliers to produce 15 percent of their energy from renewable sources, 4 percent of which can come from efficiency, by the year 2020.

On September 12, 2007, DeGette announced that she would introduce the Colorado Wilderness Act of 2007 in Congress. The bill was unsuccessful and did not pass the committee level. She reintroduced the bill in 2009.

DeGette is a cosponsor of legislation to provide the District of Columbia voting representation. On January 24, 2007, Speaker Nancy Pelosi appointed Representative DeGette to the House Page Board.

On November 26, 2007, DeGette announced her endorsement of Senator Hillary Clinton for president and was named national co-chair of Clinton's Health Care Policy Task Force and adviser on stem-cell research. DeGette was a superdelegate to the Democratic National Convention in Denver in August 2008.

DeGette was strongly critical of the Stupak-Pitts Amendment, which places limits on taxpayer-funded abortions (except in the case of rape, incest, or life of the mother) in the context of the November 2009 Affordable Health Care for America Act.

On January 12, 2021, DeGette was named an impeachment manager (prosecutor) for the second impeachment trial of President Trump.

Political positions DeGette is a member of the Congressional Progressive Caucus.

She voted with President Joe Biden's stated position 100% of the time in the 117th Congress, according to a FiveThirtyEight analysis.

Abortion

DeGette supports access to abortion and is the co-chair of the Pro-Choice Caucus. DeGette and her former co-chair, Louise Slaughter, are the sponsors of the Prevention First Act. This act aims to decrease the number of unintended pregnancies, abortions and sexually transmitted diseases through better women's healthcare. The NARAL Pro-Choice America PAC endorsed DeGette and gave her a 100% approval rating based on her positions. DeGette also received a 100% rating from Planned Parenthood. DeGette says "we must pass common-sense embryonic stem cell research legislation, placing these regulations into statute and once and for all, ensuring this critical life-saving research can be conducted for years to come, unimpeded by political whims or naysayers." DeGette and Charlie Dent introduced the bipartisan Stem Cell Research Act of 2011, which would provide lasting support for stem cell research.

Gun control DeGette supports bans on semi-automatic firearms like those used in the 2012 Aurora, Colorado shooting, which happened in a movie theater near her district. DeGette has stated that "the sole purpose of these guns and these magazines is to kill people." DeGette and Carolyn McCarthy introduced the Stop Online Ammunition Sales Act of 2012. The Brady Campaign endorsed DeGette's reelection in 2008, 2010, and 2012.

In 2013, DeGette drew national attention after making an erroneous statement at a public forum about firearm magazine restrictions. She stated, "hese are ammunition, they're bullets, so the people who have those now, they're going to shoot them, so if you ban them in the future, the number of these high-capacity magazines is going to decrease dramatically over time because the bullets will have been shot and there won't be any more available."

Healthcare DeGette has co-sponsored the Medicare for All Act, a single-payer healthcare plan.

Israel DeGette voted to provide Israel with support following the October 7 attacks. She voted against a standalone bill that would have provided aid to Israel in November 2023, saying it ignored the humanitarian needs in Gaza, Ukraine and more. DeGette voted for a combined bill that sent aid to Israel, Gaza, Ukraine and Taiwan in April 2024. She said the bill would "streamline aid to combat Putin’s aggression while sending important resources to Israel, Gaza, Taiwan, and beyond."

Personal life DeGette is married to Colorado Court of Appeals Judge Lino Lipinsky. They live in Denver and have two daughters together. DeGette sings in her church choir.
