"I just fired the head of the Federal Bureau of Investigation", the document, read to The New York Times by a USA official, quotes the president as saying.
Justice Department spokeswoman Sarah Isgur Flores said, "I can't confirm or deny the existence or non-existence of investigations or targets of investigations". Mark Warner (D-Va.), the committee's ranking Democrat.
The report is the latest in a steady stream of bad headlines for the White House related to the fallout of Comey's firing. He says he hopes Comey's testimony will answer some of the questions that have arisen since Comey was suddenly dismissed last week by President Donald Trump.
One government official interviewed by the Times claimed Trump's talk of "pressure" was a negotiation tactic, meant to press upon Moscow that its meddling in the 2016 elections had raised problems for the president, and to induce Russian Federation into diplomatic concessions.
On Capitol Hill, Comey was clearly the man in demand, with three committees working to seat him at their witness tables soon, two in the Senate and one in the House.
Trump met with the Russians on May 10, the day after he fired Comey.
The law enforcement investigation into possible coordination between Russian Federation and the Trump campaign has identified a current White House official as a significant person of interest, showing that the probe is reaching into the highest levels of government, according to people familiar with the matter.
Cummings said the committee's GOP chairman, Utah Rep. Jason Chaffetz, "should. have his subpoena pen ready" to obtain any White House documents related to Trump's meeting with the Russian foreign minister and ambassador.
11-year-old Lawrence boy finds drugs, calls police on father
When investigators arrived, they identified the substance as heroin mixed with Fentanyl, a potent and highly addictive opiate. Officers in MA are calling an 11-year-old boy courageous after he found illegal drugs in his dad's suitcase and called 911.
Former FBI Director Robert Mueller was named Special Counsel for the Russian Federation investigation on Wednesday.
Trump had said Thursday he was "very close" to naming a replacement and that former Connecticut Sen. However the White House said there would be no announcement Friday.
Mr Rosenstein said that though he was personally fond of Mr Comey, he thought it was "appropriate" to seek a new leader.
The Justice Department on Friday distributed prepared remarks that Rosenstein delivered to Congress in separate briefings.
In Rosenstein's meetings with lawmakers, he reiterated the scathing critique laid out in his memo concerning Comey's handling of the investigation into Clinton's use of a private email server, including Comey's July news conference announcing that the FBI would not recommend charges.
"It explicitly usurped the role of the attorney general, the deputy attorney general and the entire Department of Justice", Rosenstein said of that public announcement.
With the president departing on Friday afternoon for the first foreign visit of his presidency, focus was turning to the scope and nature of special counsel Robert Mueller's investigation into Russian interference in the USA election and links between the president's election campaign team and the Kremlin.
Massachusetts Democratic congressman Seth Moulton says Rosenstein didn't "do a lot to bolster our confidence in him". That would surely include Trump's firing of Comey.
