A member of the Republican Party, he served as the representative for New York's 22nd congressional district from 2023 to 2025.

On January 16, 2025, President-elect Donald Trump named Williams as under secretary. He was confirmed by the U.S. Senate on a 51–47 vote on September 18, 2025, and sworn in on September 26, 2025.

Elections

2022

On January 14, 2022, U.S. representative John Katko announced that he would not seek reelection in 2022, creating a vacancy. The contentious 2022 redistricting combined much of Katko's district with portions of a district represented by Claudia Tenney, whose district was divided. Tenney successfully ran in the new 24th district. Williams' home in Sennett lay in the 24th, two miles outside of the border of the 22nd; he chose to run in the 22nd, in part, to avoid a primary against Tenney. There is no legal requirement that a representative live within the district he represents, although the fact that he did not became a point of criticism. Katko, while supporting other local Republicans, remained neutral in the primary. Katko supporters endorsed Steven Wells, a local party official who had lost to Tenney in the 2016 primary, and who was seen as the party's favorite. while Williams was endorsed by the Conservative Party of New York. Campaign ads by the Republican Congressional Leadership Fund during the primary labeled Williams as out of touch and elitist for his truffle farm because it's an expensive gourmet ingredient.

In the general election, Williams faced Democratic nominee Francis Conole, also a U.S. Navy veteran. The race gained national attention. Politico and The New York Times both noted the race as particularly competitive. National PACs ran ads, including the Democratic House Majority PAC drawing more attention to truffles. and Stefanik endorsed him. But Katko did not. Debates between Williams and Conole were contentious. Conole said that Williams did not know Central New York and that his self-descriptions as a "political outsider" were bogus. Williams said that Conole's 20-year military career left him ill-equipped to handle issues of the economy and private business.

In the general election, Williams defeated Conole by a margin of 1.5%.

2024

In August 2023, Williams announced that he was running for a second term in 2024. His campaign website and Facebook page described himself as a political outsider and said his priorities included lower energy costs, a secure border, public safety, good-paying jobs, and robust infrastructure projects. Williams was widely considered the most vulnerable sitting congressman after redistricting added more Democrats to his district.

During the campaign, Williams faced criticism over his stance on abortion. He had celebrated the overturning of Roe v. Wade and said that he believes abortion ought to only be available in cases of rape, incest or medical necessity.

He lost the November 5, 2024, election to Democratic state senator John Mannion.

Tenure He was one of four Republican representatives from New York who on January 11, 2023, called for George Santos to resign in light of false biographical statements that Santos had made. On December 1, he voted yes on the successful vote to expel Santos from the House.

On September 12, 2023, when House speaker Kevin McCarthy announced an impeachment inquiry against Joe Biden, Williams said he supported the inquiry.

An analysis by LegiStorm found that Williams's office had an unusually high rate of staff turnover, ranking as the 3rd highest rate in the House. At a 2023 Christmas party in Washington, a verbal confrontation between Williams and Michael Gordon, his former chief of staff and campaign manager, was recorded by Ryan Sweeney, another former staffer. Williams said that Sweeney and Gordon had threatened to expose personal details about his daughter.

Williams said he voted for Donald Trump in the 2016 and 2020 U.S. presidential elections. He said he believes the 2020 presidential election raised questions about state election laws, adding he believed that President Joe Biden was elected legitimately.

He compared the January 6th hearings to the Moscow trials,

Abortion In his 2022 campaign, Williams said "each state, not the federal government, should decide what restrictions, if any, to place on abortion."

Gay rights Williams stated that he would've voted for the Respect for Marriage Act if he were in office soon enough to do so. He argued, "it’s just moral and decent to respect same-sex unions under the law – marriage under the law."

Gun regulation Williams said he would oppose any effort in Congress to restrict or remove access to firearms, including red flag laws and bans of assault weapons and high-capacity magazines. He has indicated that he would support stronger background checks for gun purchases. Previously the CEO of Trammell Crow Company, in 1995 Don founded the Foundation for Community Empowerment, which focuses on urban revitalization in South Dallas. After the George Floyd protests of 2020, Don Williams and other members of the Dallas business elite developed an eight-point action plan that included raising the minimum wage, banning police use of chokeholds, and expanding Medicaid in Texas.
