White supremacists have become the "most persistent and lethal" domestic security threat in the United States, Chad Wolf, acting Homeland Security secretary, told senators on Wednesday. Wolf's assessment came despite repeated statements by President Trump and Attorney General William Barr depicting "left-wing" extremists rioting over racial injustice as the nation's biggest internal security threat. Despite a series of racially motivated attacks last year, Trump said he didn't consider "white nationalism" to be a growing problem. Wolf, whom Trump has nominated to officially become the department's secretary, was accused earlier this month by a whistleblower of downplaying the threat of white supremacists. Wolf rejected the allegation during his Wednesday confirmation hearing, calling it "patently false" and "a fabrication."
