Sen. Thom Tillis (R-NC) fired back Friday at President Donald Trump’s latest criticism of the retiring centrist lawmaker, saying the president’s advisers were giving him bad policy advice ahead of the November midterms.

In a Truth Social post earlier that day, Trump claimed the “weak and ineffective” Tillis was a “Nitpicker” who is “always fighting against the Republican Party, and ME,” and that the second-term senator decided to retire after being refused an endorsement.
