The FBI says it has found no evidence of criminality in a new batch of Hillary Clinton emails, boosting her campaign two days before the election.
FBI Director James Comey told Congress his agency’s review had found nothing to alter its original conclusion.
In July, he said Mrs Clinton had been careless but not criminal in handling sensitive material on her private email server while secretary of state.
The issue flared up again with the discovery of new “pertinent” emails.
They were reportedly found on the laptop of Anthony Weiner, the estranged husband of one of the Democratic presidential candidate’s closest advisers.
Mr Comey’s letter to Congress late last month, revealing the bureau’s inquiry into Mrs Clinton’s emails had been revived, shook up the White House race and reinvigorated the campaign of Republican nominee Donald Trump.
