Sen. Thom Tillis of North Carolina announced Sunday he will not seek reelection in 2026.

The announcement came one day after Tillis voted against President Trump’s sweeping agenda bill.

Tillis was one of only two Republicans to oppose the bill, citing concerns over Medicaid cuts affecting his constituents.

Trump responded by threatening to support a primary challenger to Tillis’ Senate seat.

Tillis said the decision to step down was 'not a hard choice' and expressed a desire to spend more time with family.

He emphasized wanting 'the pure freedom to call the balls and strikes as I see fit' during his remaining time in office.

Tillis has served as a U.S. Senator from North Carolina since 2015.

His Senate seat is considered critical in the 2026 election as Republicans try to hold their narrow majority.

Tillis’ departure sets the stage for a high-stakes, competitive race in the battleground state.

The Republican field for his replacement is expected to draw national attention following his exit announcement.
