President Donald Trump officially nominated Christopher Wray as the new head of the FBI on Monday. Trump first announced his intention to nominate Wray three weeks ago, describing him in a tweet as “a man of impeccable credentials.” Wray formerly served as assistant attorney-general in charge of the Criminal Division at the Justice Department under former President George W Bush. During his tenure, Wray oversaw several major corporate fraud investigations, including the federal prosecutions of executives involved in the Enron scandal. Wray’s nomination must now be confirmed by the Senate. If he is confirmed, Wray will take over for Andrew McCabe, who has been the bureau’s acting director since Trump fired James Comey on May 9. In a statement released by the Justice Department, Wray said he was “honored and humbled” to be nominated.
