Republican Sen. Thom Tillis said he won't seek reelection after opposing President Donald Trump's major new tax and spending bill, which advanced in the Republican-controlled Senate Saturday night.

The decision creates a political opportunity for Democrats seeking to bolster their numbers in the 2026 midterm elections.

WASHINGTON (AP) — Republican Sen. Thom Tillis of North Carolina said Sunday he will not seek reelection next year, a day after announcing his opposition to President Donald Trump’s tax breaks and spending cuts package because of its reductions to health care programs.
