From 1h agoOpening summary: Trump tightens grip on GOP after Thomas Massie defeated in Kentucky primaryGood morning, and welcome to our live coverage of US politics. Donald Trump has tightened his grip on the Republican party after the independent-minded Congressman Thomas Massie was defeated in the Kentucky Republican House primary by the president’s hand-picked challenger.Massie lost by a vote of 55% to 45%, in what became the most expensive House primary in US history, reportedly drawing over $32m in spending.Trump repeatedly called for voters to back Ed Gallrein, a retired navy Seal and farmer, over the incumbent Massie who had drawn the president’s ire after breaking with him on several high-profile issues, including the war on Iran, the release of the Epstein files and his signature tax bill.“There is a yearning in this country for somebody who will vote for principles over party,” Massie said in his concession speech.“If the legislative branch always votes whichever way the wind is blowing, then we have mob rule,” he added.Massie’s defeat was the latest in a series of successful proxy battles Trump has fought which have ousted dissenting Republican incumbents – in states like Indiana and Louisiana – by endorsing a more loyal challenger.Thomas Massie speaks with supporters after his concession speech in Hebron, Kentucky.
