The man leading the probe into alleged Russian interference in the US election has asked for special documents pertaining to Donald Trump's conduct in high-profile incidents from the White House.
Robert Mueller has asked the seat of the executive to provide records of the US President's sacking of former FBI director James Comey, according to The New York Times.
He has also requested the White House to give the inquiry information about a meeting between Trump's son and a lawyer who was reported to be affiliated with the Kremlin.
Mueller, who served as head of the FBI between 2001 and 2013 and was tasked with heading up the Russia inquiry in May, has reportedly shown a keen interest in files pertaining to Trump's former national security advisor Michael Flynn and the head of his election campaign, Paul Manafort.
The Times is reporting Trump's lawyer has vowed to turn over records, but an official statement has seen him decline to comment on present investigations.
Donald Trump has branded all accusations regarding links to Russia as "fake news" in the past.
Meanwhile, the Kremlin has voraciously denied all allegations of involvement in the election.
