Trump fired FBI Director James Comey last week, prompting some to call for an independent prosecutor to lead the investigation.
And on Tuesday, with that latest report fanning the flames on the growing fallout from Trump's decision to terminate Comey, Deputy Attorney General Rod Rosenstein announced he was appointing former FBI Director Robert Mueller to oversee the Department of Justice investigation into Russian meddling in the 2016 presidential election.
As well as being accused of obstructing the investigation into Flynn and possible collusion with Russia, this week saw reports that Trump had disclosed highly classified information in a meeting last week with Russian Foreign Minister Sergey Lavrov and ambassador to the U.S. Sergey Kislyak.
But Mueller and Comey have been longtime allies dating back to at least 2003 when the men both worked in Washington, D.C., Mueller as FBI Director and Comey as Deputy Attorney General.
"But when I made that decision, I actually thought it would be a bipartisan decision".
The House Intelligence Committee, meanwhile, requested documents from the Justice Department and FBI about the bureau's investigation and any records related to Comey's dismissal.
President Donald Trump is assailing the naming of a special counsel as "the single greatest witch hunt of a politician in American history!"
Republican Richard Burr of North Carolina, chairman of the Senate Intelligence Committee, and Mark Warner of Virginia, the ranking Democrat, said the panel will continue its own investigation and "engage with Director Mueller" on any potential conflicts. Trump said on Twitter on Thursday morning Washington time (Friday AEST).

Trump called the multiple inquiries into Russian meddling in the United States election a "witch hunt" that's unnecessarily dividing the country. Trump fired Comey last week, suggesting his decision was motivated by the FBI's investigation into possible collusion between Russian Federation and his campaign. "You can't let them get you down, can't let the critics and the naysayers get in the way of your dreams".
There's a view in Moscow that "given the hard position Trump is in, there may be no point in going ahead with serious dialogue", said Andrei Kortunov, who runs the Russian International Affairs Council, a research group set up by the Kremlin. "Russian Federation is fine but whether it's Russian Federation or anybody else, my total priority, believe me, is the United States of America".
