As CNBC adds, Donald Trump seized on the news Friday that the FBI is probing new emails related to Hillary Clinton's private server, contending that she threatens United States security and cannot be trusted in the White House. "I have great respect for the fact that the FBI and Department of Justice are now willing to have the courage to right the horrible mistake that they made," Trump said at a rally in New Hampshire. "This was a grave miscarriage of justice that the American people fully understood and is about to be corrected."
"In connection with an unrelated case, the FBI has learned of the existence of emails that appear to be pertinent to the investigation. I am writing to inform you that the investigative team briefed me on this yesterday, and I agreed that the FBI should take appropriate investigative steps designed to allow investigators to review these emails to determine whether they contain classified information, as well as to assess their importance to our investigation," Comey wrote.
