Trump attacks Massie as Republican critic describes ‘desperate’ attempts to oust him from primary

US president writes vote the bum out' as congressman faces close race against Trump-endorsed Republican

With two days to go before the next big test of Donald Trump's iron grip over his party, the president went head-to-head on Sunday with his nemesis, Thomas Massie the Kentucky congressman who is in a fight for his political life in Tuesday's Republican primary.

Over an eight-hour period starting in the early hours of Sunday, Trump took to his bully pulpit on Truth Social to taunt Massie, one of very few senior Republicans who has dared to defy him. Massie is the worst and most unreliable Republican Congressman in the history of our Country", the rant began, followed by a mid-morning exhortation to Kentucky voters to vote the bum out on Tuesday".
