Sources have told The Washington Post that Trump has grown frustrated with the FBI director for the bureau's failure to give his election campaign a boost by announcing that Democratic presidential candidate Joe Biden, and his son Hunter Biden, are under investigation over their links to the Ukrainian energy firm Burisma.
According to the report, Trump considers Wray to be one of his worst personnel picks, and both White House chief of staff Mark Meadows and top Trump adviser Dan Scavino have also criticised Wray in internal communications.
Prior to this, on 14 October, the New York Post published two leaked emails purporting to be a correspondence between Hunter Biden and a leading official at Burisma. In the May 2014 email, Burisma board adviser Vadym Pozharskyi asked Hunter Biden to use his influence to support the Ukrainian company politically. In another email, dated April 2015, he thanked the younger Biden for arranging a meeting with his father. It is not clear if the meeting ever took place. The Biden campaign has since denied that there was a meeting.
The FBI also conducted a probe into then-Democratic candidate Hillary Clinton's personal emails back in 2016, ahead of the election that saw Trump emerge triumphantly.
