President Donald Trump fired FBI Director James Comey on Wednesday, accusing the former FBI chief of mishandling the investigation into Hillary Clinton’s private email server.
Trump, who had been in Washington, D.C., for the start of a two-day trip, was expected to speak to Comey at 2 p.m.
He told reporters that the president “just wanted to say thank you for doing what you’re doing.”
Trump said the FBI director should “get the hell out of here.”
“It’s just a witch-hunt,” Trump said.
“And the American people are going to be treated fairly.”
Comey, who was fired by Trump in May for failing to stop the Russia investigation, did not respond to requests for comment.
