Republican Rep. Thomas Massie of Kentucky has enlisted help from a key ally, Sen. Rand Paul, as he tries to fend off President Donald Trump’s threats to oust him from Congress. Massie is running headlong into his toughest political fight. A super PAC launched by Trump aides has attacked him and he awaits a yet-to-be-known challenger whom Trump has said he would endorse. Massie on Thursday wraps up a two-day swing through his district alongside Paul, who has endorsed the congressman and shares Massie’s libertarian leanings. Massie says Paul’s endorsement of him offers “a counterbalance to Donald Trump’s presumed endorsement for somebody else.”
