President Trump said Monday he will "lead the charge" to oust Rep. Thomas Massie (R-Ky.) for his refusal to support Republicans' government funding bill. Why it matters: A doctrinaire libertarian, Massie has been a persistent thorn in the side for both Trump and House Speaker Mike Johnson (R-La.) by defecting on key votes and imperiling major GOP legislation. "Congressman Thomas Massie, of beautiful Kentucky, is an automatic 'NO' vote on just about everything," Trump said in a post on Truth Social. Trump said Massie "SHOULD BE PRIMARIED, and I will lead the charge against him." He compared the Kentucky Republican to "Liz Chaney [sic]," the Republican former Jan. 6 committee member whom he helped oust.
