Donald Trump has dismissed FBI director James Comey because of his handling of the investigation pertaining to Hillary Clinton's emails.
The surprise move came from the White House overnight, making Comey the second FBI director to be fired from his position.
The former director was reported to have been addressing FBI agents in Los Angeles when the news was announced on television.
The 56-year-old is believed to have thought the news was a joke or prank at first, but then received an official letter from the president to say he had been "terminated and removed from office, effective immediately."
The decision comes after it was revealed Comey had given inaccurate information to Congress about the inquiry into the former Democratic candidate's emails.
Attorney General Jeff Sessions was a factor in the President's decision, having advised him that Comey was not capable of effectively leading the FBI.
Comey caused a stir after he announced the investigation would be re-opened merely 11 days before America went to the polls in November last year.
