Thomas Roland Tillis ( TIL-iss; born August 30, 1960) is an American politician serving as the senior United States senator from North Carolina, a seat he has held since 2015. A member of the Republican Party, Tillis served in the North Carolina House of Representatives from 2007 to 2015, and as its speaker from 2011 to 2015. As speaker of the North Carolina House of Representatives, Tillis led the Republican effort to block the expansion of Medicaid and worked to introduce restrictions on abortion, stringent voting requirements, and a constitutional amendment banning same-sex marriage. Tillis was elected to the Senate in 2014, defeating Democratic incumbent Kay Hagan, and reelected in 2020, defeating Democratic nominee Cal Cunningham. He became the state's senior U.S. senator when Richard Burr retired in 2023. In the Senate, Tillis has sought to repeal the Affordable Care Act, proposed a 15-year pathway to citizenship for some undocumented youth as a more conservative alternative to the bipartisan DREAM Act, and voted for the Bipartisan Safer Communities Act, which provided state funding for red flag laws, crises intervention orders and school safety resources. Tillis initially opposed President Donald Trump's national emergency declaration to divert funding to a border wall, but voted for it after pressure from his party. His views on same-sex marriage evolved over time, and in 2022 he voted for the Respect for Marriage Act, which repealed the Defense of Marriage Act and codified same-sex and interracial marriage into federal law.
