"Chris Christie's Provocative Jab at Trump's Achilles' Heel"

Former New Jersey Gov. Chris Christie taunts Donald Trump after the former president called for him to drop out of the Republican presidential race. Christie claims to be living "rent-free" in Trump's head and says Trump can't stand when someone credible criticizes him. Christie highlights his successful track record as a U.S. attorney and suggests that Trump should consider dropping out of the race due to his upcoming federal election interference trial. Despite polling behind other candidates, Trump continues to focus his attention on Christie, who was once a close ally but turned into a critic after Trump's presidency.
