Republican Senator Thom Tillis of North Carolina has adopted a more outspoken role in Congress after announcing he will not seek re-election, following a threat from Donald Trump to back a primary challenger. Tillis, who broke with the president on his 2025 spending bill, has since become a vocal critic of Trump administration officials and policies, though he stops short of criticising Trump himself.
In a recent Senate hearing, Tillis delivered a fierce rebuke of Homeland Security Secretary Kristi Noem, calling her leadership a “disaster”. He had previously called for her resignation after immigration agents killed two US citizens in Minneapolis. Tillis has also criticised White House aide Stephen Miller and is blocking the nomination of Kevin Warsh to lead the Federal Reserve over objections to the Justice Department investigating current chair Jerome Powell.
“When I disagree, I disagree. Now I just have fewer constraints on the wordsmithing I have to do before I say something,” Tillis said, acknowledging his new freedom. His denunciations have placed him alongside Republican dissenters Lisa Murkowski and Susan Collins.
Tillis, 65, a former management consultant, says his aim is to help Trump succeed by speaking truth. “I can speak truth to a president that I hope goes down in history as the most successful Republican president,” he said on the Senate floor in January. His political adviser Paul Shumaker noted that Tillis is now able to be more vocal without worrying about political dynamics.
Democrats hope to win Tillis’s seat in the November midterm elections as part of their bid to retake the Senate majority, but Tillis insists his criticism is meant to benefit Trump, not the opposition.
