Trump had already been threatening North Carolina Sen. Thom Tillis with a primary challenge, and posted Sunday that Tillis' announcement was “Great News!”

Republican Sen. Thom Tillis of North Carolina says he won't seek reelection. That news Sunday comes one day after he announced his opposition to President Donald Trump’s tax breaks and spending cuts package because of its reductions to health care programs.

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.
