Bill Clinton has criticized FBI Director James Comey's decision to send a letter to Congress just days before the election about possible new evidence in the investigation into Hillary Clinton's email server. After a review of newly discovered emails that surfaced while investigating another case, the FBI ultimately concluded that it would stand by its decision not to recommend charges against the former secretary of State.

Hillary Clinton's campaign has largely blamed Comey's letter for losing the election.
