US President Donald Trump has appeared to confirm he is under investigation for obstruction of justice, claiming he is being investigated for firing FBI director James Comey by the man who told him to do it.
- Mr Trump earlier tweeted "nobody has been able to show any proof" of collusion with the Russians
- The tweets are the latest in a week of angry social media responses by the President over a report that Mr Mueller was looking into whether Mr Trump obstructed justice
- The President complained the probe was unfair
Mr Mueller was appointed special counsel to investigate Russian involvement in the 2016 presidential election and possible collusion by Trump campaign associates with the Russians, but there has been no indication that Mr Mueller told Mr Trump to fire Mr Comey.
"I am being investigated for firing the FBI Director by the man who told me to fire the FBI Director! Witch Hunt," the President wrote in his tweet on Friday morning (local time).
In another tweet earlier on Friday, Mr Trump wrote: "After 7 months of investigations & committee hearings about my 'collusion with the Russians,' nobody has been able to show any proof. Sad!"
Deputy Attorney-General Rod Rosenstein submitted a widely circulated memo to the President last month raising concerns over Mr Comey's performance, but Mr Trump later asserted that he had already made the decision himself to fire Mr Comey.
The White House confirmed that Mr Mueller was among the candidates Mr Trump interviewed to replace Mr Comey.
A day later, Mr Rosenstein appointed Mr Mueller — who was at the helm of the FBI during the September 11 attacks — as special counsel.
'Single greatest witch hunt'Friday's tweets are the latest in a week of angry social media responses by the President over a report by The Washington Post that Mr Mueller was looking into whether Mr Trump obstructed justice.
The President complained the probe was unfair and wondered why his defeated Democratic opponent was not getting the same scrutiny.
"Why is that Hillary Clinton's family and Dems dealings with Russia are not looked at, but my non-dealings are?" he asked."They made up a phony collusion with the Russians story, found zero proof, so now they go for obstruction of justice on the phony story. Nice," Mr Trump wrote in his first tweet.
"You are witnessing the single greatest WITCH HUNT in American political history — led by some very bad and conflicted people! #MAGA."
The Twitter attacks came as Vice-President Mike Pence hired a personal lawyer to represent him in the intensifying investigation.
Mr Pence's office confirmed he had retained Richard Cullen, a former Virginia Attorney-General and US attorney for the Eastern District of Virginia, to assist "in responding to inquiries" from Mr Mueller.
