Donald Trump attacks the 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.

Tainted (no, very dishonest?) FBI “agent’s role in Clinton probe under review.” Led Clinton Email probe. @foxandfriends Clinton money going to wife of another FBI agent in charge.

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!"

After years of Comey, with the phony and dishonest Clinton investigation (and more), running the FBI, its reputation is in Tatters - worst in History! But fear not, we will bring it back to greatness.

The president also retweeted a tweet suggesting FBI director Chris Wray "needs to clean house".

The president said earlier today 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.
