But according to charging documents filed Friday by special counsel Robert Mueller, a "very senior member of the Presidential Transition Team" and another "senior" member of the same team directed Flynn to call Russian officials or counseled Flynn on how to discuss sanctions with the Russians.
But a former Obama administration Justice Department official, Matthew Miller, said Mr Trump's tweeted response may have "admitted to obstruction of justice".
The president had previously maintained that he fired Flynn in February for lying to Pence.
US President Donald Trump has said actions by his disgraced former national security adviser Michael Flynn during the presidential transition were lawful and there was no collusion between his 2016 White House campaign and Russian Federation. "I hope you can let this go", the US President allegedly said to the Federal Bureau of Investigation director when they were alone in the Oval Office. When Mr. Trump fired his F.B.I. director, James B. Comey, in May, he initially cited his handling of the Clinton email investigation as the reason for his dismissal.
At the time, Pence said Trump was justified in firing Flynn because Flynn had lied to him.

The Impeach-O-Meter is a wildly subjective and speculative daily estimate of the likelihood that Donald Trump leaves office before his term ends, whether by being impeached (and convicted) or by resigning under threat of same. "So we're very happy", he said.
"I hope you can see your way clear to letting this go, to letting Flynn go". It's unclear what, if anything, Trump believes Flynn lied about, if he had nothing to hide.
The White House has disputed Mr Comey's testimony.
Vladeck added: "I can't speak to how the special counsel would view this statement, but it betrays an alarming lack of understanding of the relevant legal rules on the President's part, or of the serious legal jeopardy he could be in for actions he may wrongly believe are appropriate".
The trio of fundraisers was a sort of victory lap for Trump, who has long spoken animatedly about his desire to reform the tax code, especially since GOP efforts to repeal and replace the Affordable Care Act floundered in Congress earlier this year.
Flynn, who was sacked from the White House in February, also acknowledged publicly for the first time that he is cooperating with Mueller's team, prompting speculation about what information Flynn could share with investigators.
