President Trump has scored another win against a Republican rival, defeating Rep. Thomas Massie in Kentucky’s primary and knocking out one of his most outspoken critics on Capitol Hill. Massie had been a particularly difficult thorn in Trump’s side. He pushed for the release of the Jeffrey Epstein files, opposed the war with Iran, and voted against Trump’s signature tax legislation last year. He lost Tuesday to Trump-backed challenger Ed Gallrein following the most expensive U.S. House primary in history.
