President Donald Trump was angry on Tuesday after Rep. Thomas Massie (R-KY) — a sharp critic of the president — pointed out that Trump had endorsed him in the past.Massie, an incumbent lawmaker fighting to maintain his congressional seat as a Republican representing Kentucky, has been going up against Trump-backed candidate Navy SEAL Ed Gallrein in a heated primary that's been called the most expensive House primary in history.Hours before polls were set to close, Trump tore into Massie, who has publicly questioned the president's ties to late financier and convicted child sex offender Jeffrey Epstein, the Iran war and the country's affordability crisis. The president lambasted the longtime GOP leader on his Truth Social platform. "Horrible Congressman Thomas Massie put out an old Endorsement, from many years ago, of him by me long before I found out that he was the Worst Congressman in the History of our Country," Trump wrote. "I endorsed Ed Gallrein, a true American Patriot, which Massie knows full well, so the statement that he put out is fraudulent, just like HE is fraudulent. WITHDRAW YOUR FAKE STATEMENT, MASSIE, RIGHT NOW! President DONALD J. TRUMP."
