Tenure
Timmons was sworn into office on January 3, 2019, amid a government shutdown. He cosponsored legislation to require Congress to balance the budget, defund Planned Parenthood, support Gold Star Families, strengthen national defense, and promote school choice.
Timmons serves on the Financial Services Committee, where he introduced legislation seeking to counter China's efforts to expand its 5G influence in countries receiving assistance from international financial institutions. He was elected by his classmates to represent the freshman class on the Republican Steering Committee.
He introduced legislation proposing an amendment to the Constitution of the United States to limit the number of consecutive terms that a member of Congress may serve (H.J.Res.86).
Timmons supported President Donald Trump during his first impeachment, saying of the process, "It is very, very, very broken" (referring to his 2018 campaign slogan "Washington is broken"). He added that he thought the process would be fair in the Senate and called the opposition to impeachment "bipartisan."
In December 2020, Timmons 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 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.
In January 2021, Timmons announced he would object to the certification of Biden as president. When Congress reconvened after the storming of the United States Capitol, Timmons voted to object to the Electoral College results.
In July 2024, Timmons questioned former Secret Service Director Kimberly Cheatle at a House Oversight Committee hearing. His comments gained national attention as Cheatle resigned the next day following fiery questioning from congressional leaders.
