(CPAC) in National Harbor, Maryland.
2020 presidential election and aftermath In December 2020, Buck was one of 126 Republican members of the
House of Representatives to sign an
amicus brief in support of
Texas v. Pennsylvania, a lawsuit filed at the
United States Supreme Court contesting the results of the
2020 presidential election, in which
Joe Biden defeated incumbent
Donald Trump. The Supreme Court declined to hear the case on the basis that Texas lacked
standing under
Article III of the Constitution to challenge the results of an election held by another state. Buck later became one of a group of seven Republicans who did not support their colleagues' efforts to challenge the results of the election on January 6, 2021. These seven signed a letter that, while giving credence to election fraud allegations Trump made, said Congress did not have the authority to influence the election's outcome. In a 2021 interview with
Kara Swisher of
The New York Times, Buck distanced himself from Trump's
claims regarding the 2020 election. After
Liz Cheney was ousted as Republican Conference Chair for refusing to accept Trump's claims of a stolen election, Buck likened her ouster to
cancel culture, further stating that the decision would alienate voters who agreed with Cheney's stance. After Trump was
indicted for attempting to overturn the 2020 presidential election in Georgia, Buck distanced himself from comments made by fellow members of the House Freedom Caucus, which accused federal law enforcement of targeting Trump, saying that he trusted the process to take its course. Prior to the first nomination election for the
October 2023 Speaker of the House election, Buck asked the two Republican candidates,
Steve Scalise and
Jim Jordan, if the 2020 election was legitimate. Both Scalise and Jordan voted against certifying the results. Buck told reporters that they avoided answering his question. He thus voted "present" in the nomination election and later did not vote for Jordan in any of the votes of the full House. Buck would, however, vote for
Mike Johnson, who voted against certifying the 2020 election and organized failed lawsuits to reverse the election results in key states. When asked about his about-face support of an election denier, Buck said Johnson's actions were mistakes, but they did not disqualify him from the speakership, and claimed Johnson's actions were not as significant as the moves Jordan took to overturn the election. Buck also stressed the need to elect a speaker and pass legislation once again.
Abortion Buck opposes
abortion, including in cases of
rape and
incest, but makes exceptions if the mother's life is in danger.
Antitrust Buck favors bipartisan legislation designed to bolster the federal government's ability to bring
antitrust cases against "
Big Tech" companies. Buck supports the proposed
American Innovation and Choice Online Act. In 2023, Buck and Representative
David Cicilline co-founded the Congressional Antitrust Caucus.
COVID-19 Buck opposed many of Colorado's COVID-19 restrictions, including the closing of businesses. Of COVID-19 restrictions, he told
The Denver Post, "we went like lambs to the slaughter. We can't allow that to happen again". Buck voted against the
American Rescue Plan Act of 2021, calling it "funding for pet projects in Nancy Pelosi and Chuck Schumer's home states, money for Obamacare subsidies and Planned Parenthood, and stimulus checks for prisoners and illegal immigrants".
Education Buck supports a revamp of the
Department of Education and questions the department's constitutionality. According to a Buck spokesman, "Ken believes there is global warming but thinks the evidence points to it being natural rather than man-made."
Foreign policy In 2020, Buck voted against the National Defense Authorization Act of 2021, which would prevent the president from withdrawing soldiers from
Afghanistan without congressional approval. In 2021, during a House vote on a measure condemning the
Myanmar coup d'état that overwhelmingly passed, Buck was among 14 Republican representatives who voted against it, for reasons reported to be unclear. In June 2021, Buck was one of 49 House Republicans to vote to repeal the
Use of Military Force Authorization against Iraq. In September 2021, Buck was among 75 House Republicans to vote against the National Defense Authorization Act of 2022, which contains a provision that would require women to be drafted. Buck was among 19 House Republicans to vote against the final passage of the 2022 National Defense Authorization Act. In 2023, Buck was among 47 Republicans to vote in favor of H.Con.Res. 21, which directed President
Joe Biden to remove U.S. troops from
Syria within 180 days. Buck voted to provide Israel with support following
2023 Hamas attack on Israel. Buck's last action as a congressman was to sign discharge petitions that would force votes on bills supplying military aid to Ukraine, Israel, and Taiwan.
Guns Buck opposes gun control and is endorsed by
Gun Owners of America. He has said he would "oppose any federal legislation to compile a database of gun owners or to further proscribe Americans' freedoms under the
Second Amendment".
Healthcare Buck opposes the
health care reform laws enacted in 2010. He instead favors
free market-based reforms. While running for Senate in 2010, Buck's campaign website stated, "We need to let the market work, make people responsible for their own insurance, and restore Americans' freedom to decide for themselves whether and how much insurance to buy." He supported a state constitutional amendment that would give rights to unborn
fetuses, but then later withdrew his support reportedly after he found out that the measure would have restricted certain fertility and
contraception procedures.
LGBT rights Buck supported the U.S. military's "
Don't ask, don't tell" policy. He said, "I do not support the repeal of don't ask don't tell. I think it is a policy that makes a lot of sense." Buck believes that being gay is a choice. He said, "I think birth has an influence over it, like
alcoholism ... but I think that basically you have a choice." The
Log Cabin Republicans have rebuked him for this comment. In 2015, Buck condemned the Supreme Court decision
Obergefell v. Hodges, which held that same-sex marriage bans violate the constitution. On June 19, 2022, Buck voted against The Respect for Marriage Act, a bill that would protect the right to gay marriage at a federal level. In 2021 Buck opposed the
Equality Act, arguing that the legislation would force doctors to treat LGBT patients despite their religious objections, comparing it to forcing Jewish doctors to treat Nazi patients. In 2023 Buck cosponsored the Protection of Women and Girls in Sports Act of 2023, which is a nationwide ban on transgender and intersex girls and women from participating in girls and women's sports.
Net neutrality Buck signed his support for Ajit Pai's motion to abolish
net neutrality, alongside 106 other Republican representatives. When asked about Pai's work to unravel net neutrality rules, Buck said: "I support Chairman Pai's efforts to free internet providers from burdensome regulations that stifle innovation and increase costs for Coloradans."
National security During debate over the
USA FREEDOM Reauthorization Act of 2020, Buck offered an amendment to the title of the bill so as to read: "A bill to be known as the Federal Initiative to Spy on Americans (FISA) Act." With only 35 votes in favor, the amendment was not adopted.
Veterans' health Buck proposed privatizing
Veterans Administration hospitals so they would "be better run". Three months later, he changed positions and his campaign said, "while Buck does indeed believe that private sector providers might do a better job than the VA in delivering health care to veterans, he is not in favor of fully privatizing health care for veterans."
Congressional prohibition on stock trading The congressman supports a prohibition on members of Congress trading in stocks.
Fiscal Responsibility Act of 2023 Buck was among the 71 Republicans who voted against final passage of the
Fiscal Responsibility Act of 2023 in the House. ==Personal life==
