With more than 13,000 individual campaign contributions, Tillis announced Sunday he will not be seeking a third term next year.

W ASHINGTON—Centrist Sen. Thom Tillis (R., N.C.) said he won’t seek re-election in 2026, less than 24 hours after he voted against a motion to advance President Trump’s tax and spending megabill, drawing public backlash from the president.

Senate Majority Leader John Thune said Tillis gave him a heads-up he would retire: “It’s unfortunate, and it’s something he’s been thinking about for a while and he just finally decided that was the best decision for him and his family,” he told POLITICO.
