Democrats are pressing the Director of National Intelligence Dan Coates to assess the impact of President Trump sharing highly classified information with Russian officials during an Oval Office meeting last week.
Flynn first made the disclosure on 4 January to the transition team's chief lawyer, Donald McGahn II, who is now the White House counsel, the New York Times reported.
Despite knowing of the investigation, Trump appointed Flynn his first national security adviser. "While the president has repeatedly expressed his view that General Flynn is a decent man who served and protected our country, the president has never asked Mr. Comey or anyone else to end any investigation, including any investigation involving General Flynn", a White House statement said. Trump eventually signed off on the mission, but only after Flynn was sacked.
Flynn, a retired Army general, is one of several of Trump's associates that are being investigated by federal officials for their potential links to foreign governments and Russia's interference into the presidential election.
Trump's freakish loyalty to Flynn has been a recurring theme in a number of scandals - most recently former FBI Director James Comey's claim that Trump urged him shut down the federal probe into Flynn a day after the national security adviser resigned. It's unclear why Flynn gave the order, but Turkey happens to oppose the move, arguing that the Kurdish forces have ties to a terrorist group. The Trump administration kept Flynn on for another 18 days, then fired him, ostensibly because he'd misled Vice-President Mike Pence.
A month later he filed retroactive paperwork admitting that he worked as a foreign agent representing the interests of the Turkish government in a dispute with the U.S.
Flynn told Rice to delay approving the mission.
Flynn held the position for only 24 days..
Also Tuesday, in an extraordinary turn of events, Russian President Vladimir Putin offered to turn over to Congress records of Trump's discussions with the diplomats.
Trump last week fired James Comey from his post as FBI director, explaining that it was partly because of the Russian Federation investigation. He was ultimately paid more than $500,000 to advocate for the Turkish government.
Flynn was paid $45,000 by RT in 2015 for a speech.
