Donald Trump has responded to a guilty plea by his former national security adviser Michael Flynn, saying Mr Flynn’s actions as a member of his transition team “were lawful”.
Mr Flynn has entered a plea deal and agreed to co-operate with an inquiry into alleged collusion with Russia.
The deal, for a lesser charge than he might have faced, prompted speculation that he has incriminating evidence.
The president wrote on Twitter on Saturday that he had “nothing to hide”.
Mr Flynn is co-operating with Special Counsel Robert Mueller, who is leading an investigation into alleged ties between the Trump campaign and Russia ahead of the 2016 election.
On Saturday, a day after Mr Flynn’s indictment, it emerged that a veteran FBI agent had been dismissed from Mr Mueller’s team after the discovery that he had sent anti-Trump text messages.
Peter Strzok was removed from the investigation in summer, a spokesman for the special counsel’s office, told theNew York Times.
Russia scandal rears its head
Saturday was a momentous day for Mr Trump, after his sweeping tax reform billfinally scraped through the senate in the early hours of the morning with 51 votes to 49.
But as he left the White House hours after the vote he was quick to address Michael Flynn’s admission the day before of lying to the FBI. “What has been shown is no collusion, no collusion. There has been absolutely no collusion. So we’re very happy,” he told reporters.
In denying that Mr Flynn had acted unlawfully as part of his transition team, Mr Trump appeared in his tweet to admit that he knew the former general had lied to the FBI before he fired him in February – contradicting the president’s account at the time.
I had to fire General Flynn because he lied to the Vice President and the FBI. He has pled guilty to those lies. It is a shame because his actions during the transition were lawful. There was nothing to hide!

Analysts say if Mr Trump knew that Mr Flynn had lied to the FBI, at a time when he appeared to pressure then-FBI director James Comey to drop the agency’s investigation into the former general, it could amount to obstruction of justice by the president.
Matthew Miller, a former Obama administration Justice Department official, said in a tweet: “Oh my god, he just admitted to obstruction of justice. If Trump knew Flynn lied to the FBI when he asked Comey to let it go, then there is your case.”
Sources close to the president told the Washington Post that the tweet had been drafted by Mr Trump’s personal lawyer, John Dowd, who later apologised and said he should have been more careful with his language. The White House has yet to comment.
Meanwhile,the New York Times reportedthat it had obtained internal emails sent by Mr Trump’s transition team that disputed the White House assertion that Mr Flynn acted alone in his contacts with Russian officials.
In one email quoted by the paper, a senior adviser appeared to say that Russia had “just thrown the U.S.A. election to him”, referring to Mr Trump.
A White House lawyer told the paper that the adviser, KT McFarland, had meant only that the Democrats were portraying it that way.
The plea deal
Under the terms of the plea deal with Mr Mueller, Mr Flynn admitted making false statements to the FBI, a significantly lesser charge than he might have faced for illegally dealing with Russian officials.
Analysts say the deal suggests that the former general has evidence implicating one or more senior members of the Trump administration.
Mr Flynn has admitted lying about his contact with the Russian ambassador Sergei Kislyak in December 2016 – after Mr Trump was elected but before he became president.
The charging documents against Mr Flynn state that he was directed to make contact with Russian officials by a “very senior member” of the Trump transition team.
Several US news organisations report the very senior official now under the spotlight is Jared Kushner – Mr Trump’s adviser and son-in-law.
US intelligence agencies say Russia’s President Vladimir Putin directed a state effort to influence the US election in favour of Mr Trump.
Mr Trump has repeatedly denied that his campaign or transition team colluded in Russian actions.
What did Flynn do wrong?
Mr Flynn was questioned by the FBI shortly after Mr Trump took office in January about his December meetings with Mr Kislyak. He was forced to resign in February, 23 days into his job.
According to the FBI’s statement of offence signed by Mr Flynn, he discussed Russia’s response to US sanctions as well as a UN Security Council resolution on Israel, at the direction of the Trump team.
Under the Logan Act it is illegal for a private US citizen, as Mr Flynn was during the transition period, to conduct foreign affairs without the permission or involvement of the US government.
The charge of making false statements normally carries up to five years in prison, but under the terms of his plea deal Mr Flynn faces a lighter sentence of only up to six months, court filings show.
The administration has sought to distance itself from Mr Flynn. White House lawyer Ty Cobb said on Friday: “Nothing about the guilty plea or the charge implicates anyone other than Mr Flynn.”
Michael Flynn previously served in the Obama administration before being fired. Mr Obama reportedly advised his successor not to hire the former general, but Mr Trump appointed him to one of the most senior positions in the country.
Mr Flynn is not the first former Trump official to be charged. In October, Mr Trump’s former campaign manager, Paul Manafort, and his business associate Rick Gates were accused of conspiring to defraud the US in dealings with Ukraine (both deny the charges).
Another ex-aide, George Papadopoulos, has also pleaded guilty to making false statements to FBI agents.
