"I hope you can let this go", Trump is said to have told Comey during the meeting in the White House. While the president does have authority to disclose classified information, there's concern that it may have damaged national security. Officials are anxious that Mr Trump's lack of focus and attention to detail could cause problems as he visits Arab leaders in Saudi Arabia, Israeli and Palestinian leaders in Israel and the West Bank, the pope at the Vatican, NATO leaders in Brussels and G7 counterparts in Sicily.
"We're a long ways from a conviction - the fact that we simply have a headline in The New York Times", Republican Representative Trey Gowdy said on Fox News.
Comey wrote that Trump asked him to end an investigation into Flynn during a February meeting in the Oval Office.
In the new memo to have emerged, Trump asks Comey to "let this go", in reference to the FBI investigation of former national security adviser Michael Flynn.
The New York Times reported on Tuesday that Trump asked Comey to shut down an investigation into Flynn and his ties with Russian Federation - an allegation White House disputed.
February 14, 2017: Comey speaks with Trump in the Oval Office a day after Flynn is ousted.
The existence of the memo was first reported Tuesday by The New York Times, which said it was drafted after a February meeting in the Oval Office. Without using the term, the newspaper was suggesting that Trump was guilty of obstruction of justice, an impeachable offense. The FBI has also probed other Trump associates for possible connections to Russian officials.
Stay tuned: The NYT highlights two key facts: (1) Comey wrote a memo after every interaction with the president, including some that remain classified, so there might be more shoes yet to drop and (2) an Federal Bureau of Investigation agent's notes are widely held up as admissible in court proceedings. One week after Comey's firing, nearly to the minute, the Times article based on the leaked Comey memo was posted on the newspaper's web site.
According to the director's notes, Comey did not respond directly to the president's entreaties, only agreeing with Trump's assertion that Flynn "is a good guy".
Criminally speaking, obstructing justice applies to a variety of scenarios - like threatening a juror, retaliating against a witness, or impeding a grand jury proceeding - and Trump's alleged request would not fit neatly into any of them, legal experts said.

Jose Mourinho sends honest message to Man United fans
The youngsters win against Spurs comes after Mauricio Pochettinio's side beat United 2-1 on Sunday afternoon at White Hart Lane. We had a fantastic record of 25 matches. "We were pushed for that situation and even the (fixtures) draw".
Republican lawmaker Jason Chaffetz, the committee head, wrote in a letter to acting FBI Director Andrew McCabe demanding that the agency produce "all memoranda, notes, summaries, and recordings referring or relating to any communications between Comey and the President".
Republicans, caught off-guard, insisted they wanted to hear from Comey, who was sacked last week a day before Trump met in the Oval Office with the Russian diplomats.
Aides are anxious that Mr Trump could end up speaking off-the-cuff and ruin the meetings, said one official.
Republicans still call the shots in Congress, however, and it's a significant leap to get them to abandon the Trump presidency and any hope of advancing their agenda for the foreseeable future.
Earlier in the day, National Security Adviser H.R. McMaster was given talking points to "try and turn the temperature down a little", one person familiar with the comments said, "without causing more of a firestorm or making news or actually denying the story". The crisis atmosphere within the administration was reflected in the fact that State Department officials were unaware of the Tillerson statement when contacted by the press.
The White House has dismissed Comey's version of events revealed by a memo that was described to CNN. While the White House initially cited a Justice Department recommendation and Comey's very public handling of the Clinton email investigation as reasons, those explanations quickly shifted.
The news provoked backlash from members of Congress, who renewed calls for Comey to testify on Capitol Hill.
Senator Bob Corker of Tennessee, chairman of the Foreign Relations Committee, said of the Trump White House, "Obviously, they are in a downward spiral right now and have got to figure out a way to come to grips with all that's happening".
"When people elected the president, they knew they were electing somebody different because they wanted things to change in Washington, and I think he has unique potential to bring change to the system and voters knew what they were doing", Blunt said.
