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.“Now he can have all the fun he wants for a few months, with some of his RINO friends, screwing the Republican Party,” Trump wrote, using the acronym for “Republicans in Name Only.”

Tillis, a frequent Trump critic, shot back in a social media post to criticize the administration’s $1.8 billion “lawfare” fund, advocating for 50-year mortgages, exchanging government-funded subsidies for stakes in public and private companies, firing “our very best generals,” and not holding Russian President Vladimir Putin accountable. He also took aim at each of the officials behind the policies.

“Mr. President, completely agree about having a lot of fun over these next seven months. But nitpicking?” Tillis posted. “If opposing these things makes me a RINO, then I gladly accept that nickname. We need Republicans to do well in November, but the stupid stuff is killing our chances!”
