Comey's written account of the meeting is two pages long and highly detailed, the associates said.
Rep. Jason Chaffetz (R-Utah), who chairs the House oversight committee, said in a Tuesday night tweet that he has his "subpoena pen ready" and was asking the administration to turn over the Comey memos.
A US Senate panel investigating possible Russian interference in US elections and possible collusion with President Donald Trump's campaign team has requested that James Comey, the sacked Federal Bureau of Investigation director, testify before its members.
Yesterday, Sen. Angus King (I-ME) told CNN yesterday that he believed impeachment procedures is on the table after news broke that former FBI Director James Comey has a memo in which Trump told him to stop investigating former United States National Security Advisor Michael Flynn.
"He is a good guy", Trump told Comey, according to the memo.
The New York Times reported Tuesday that Comey documented each phone call and meeting he had with President Donald Trump in an apparent attempt to create a paper trail of the president's efforts to sway investigators.
Trump on May 9 fired Comey, who led the FBI investigation into the ties between Russian officials and Trump's presidential campaign, an issue that Congress also addresses.
First, on its face, the idea that everyone should overlook what a sitting president says to the director of the FBI about an ongoing counter-espionage investigation is a very tough sell. The probe should clarify if President Trump and his top aides were involved in a conspiracy to obstruct justice, the lawmakers said.
White House officials staunchly defended President Donald Trump's disclosure of classified information supplied by Israel, to senior Russian officials.
"The president has the utmost respect for our law enforcement agencies, and all investigations", said the statement.
Flynn's resignation came hours after it was reported that the Justice Department had warned the White House that Flynn could be vulnerable to blackmail for his contacts with Russian Ambassador Sergey Kislyak before Trump took office.
