Andrew McCabe: Ex-FBI deputy director gave notes to Russia inquiry
Ex-FBI deputy director Andrew McCabe has given memos about conversations he had with President Donald Trump to an inquiry into alleged Russian meddling in the 2016 election, US media say.
The memos could support claims that Mr Trump sought to obstruct justice.
Mr McCabe was fired from the FBI on Friday. Mr Trump had accused him of bias and said on Sunday Mr McCabe had never taken notes when the two met.
The president has also dismissed the Russia investigation as a "witch hunt".
The investigation is led by special counsel Robert Mueller, himself a former FBI director. He has so far indicted 19 people.
The president's lawyer, John Dowd, issued a statement on Saturday saying it was time for the special counsel's investigation to end. Mr Trump has since complained that the Mueller team is composed of "13 hardened Democrats, some big Crooked Hillary supporters, and Zero Republicans".
Why was McCabe fired?
Mr McCabe had been under internal investigation by the FBI and had already stepped down from his deputy post in January pending the review.
He was sacked just two days short of his 50 birthday on Sunday, when he was expected to retire with a federal pension.
Attorney General Jeff Sessions said the "extensive and fair investigation" had concluded that Mr McCabe "made an unauthorised disclosure to the news media and lacked candour - including under oath - on multiple occasions".
Although the decision to fire Mr McCabe was made by Mr Sessions, Mr Trump had criticised him for months.
He has publicly pointed to donations that Mr McCabe's wife, a Democrat, received from a Clinton ally when she ran unsuccessfully for the state Senate in 2015 as evidence that Mr McCabe was politically biased.

In December Mr Trump tweeted: "FBI Deputy Director Andrew McCabe is racing the clock to retire with full benefits. 90 days to go?!!!"
He welcomed the news of his dismissal almost immediately after Mr Sessions announced it, calling the move a "great day for democracy".
Mr Trump's tweet about the firing provoked an angry response from former CIA director John Brennan, who implied Mr McCabe was being made a scapegoat.

What could the memos say?
News that Mr McCabe had kept records of his conversations with Mr Trump at the time he was acting FBI director emerged on Saturday.
US media say the memos will support Mr Comey's account of the circumstances of his dismissal last May.
Mr Comey has testified that Mr Trump had asked him for his "loyalty" and requested he drop an inquiry into his former National Security Advisor Michael Flynn.
He too has said he kept contemporaneous notes of his dealings with the president.
But President Trump cast doubt over the notes. Tweeting on Sunday, he said he had spent "very little time" with Mr McCabe - and the acting FBI director had never taken notes during those meetings.
He added: "Same with lying James Comey. Can we call them Fake Memos?"
"I am being singled out and treated this way because of the role I played, the actions I took, and the events I witnessed in the aftermath of the firing of James Comey," his response said.
The statement alleges that the justice department report recommending his firing was "accelerated" after he indicated that he would corroborate Mr Comey's version of events.
On Saturday Mr Comey - who is due to release a book - said Americans would soon be able to judge for themselves "who is honourable or not" after the president again criticised him on Saturday.

What did Trump say on Saturday?
The president continued posting about Mr McCabe's departure on social media, saying there had been "leaking, lying and corruption" at the FBI, as well as the defence and state departments.
In an email to The Daily Beast website, Mr Dowd said he prayed that Acting Attorney General Rod Rosenstein would follow the "brilliant and courageous example" set by Mr Sessions to bring the investigation to an end.
He initially said the statement was made on behalf of the president, before backtracking and saying the comments had been made in a personal capacity.

Mr Dowd's statement provoked an angry response from Democrats.
The statement was echoed by Sen Patrick Leahy, who said the Senate Judiciary Committee should hold a hearing on the "attempted politicisation of the FBI".
Democratic Congressman Adam Schiff tweeted: "Obstruction of justice is no less a threat to our democracy when done in the open than behind closed doors."
