Trump attacks his own FBI in series of tweets
US President Donald Trump has attacked his own FBI in a series of tweets and said the law enforcement agency's reputation was "in Tatters - worst in History!"
He added that "we will bring it back to greatness".
The president was responding to reports that a veteran FBI counter-intelligence agent was removed from special counsel Robert Mueller's team investigating Russian election meddling because of anti-Trump text messages.
Mr Trump wrote that after years under fired FBI director James Comey, "with the phony and dishonest Clinton investigation (and more)", the agency's reputation "is in Tatters - worst in History!"
The president also retweeted a tweet suggesting FBI director Chris Wray "needs to clean house".
The president said earlier on Sunday that he had never asked Mr Comey to stop investigating ex-national security adviser Michael Flynn.
Mr Comey testified before Congress in June that the president asked him if could see to "letting Flynn go".
Mr Comey said that request came a day after Mr Trump forced Mr Flynn to resign his White House post.
In a tweet on Sunday, Mr Trump said: "I never asked Comey to stop investigating Flynn. Just more Fake News covering another Comey lie!"
Mr Flynn pleaded guilty on Friday to lying to the FBI and agreed to co-operate with Robert Mueller's investigation.
Mr Trump fired Mr Comey as FBI director in May.
