Russia's Ministry of Foreign Affairs posted a photo of Trump shaking hands with Lavrov literally minutes after the meeting began. Late Thursday, The New York Times cited two unnamed Comey associates who recounted his version of a January dinner with the president in which Trump asked for a pledge of loyalty. Asked if Trump recorded conversations with Comey and if there are recording devices in the White House, Spicer did not give yes-or-no answers.
Former acting Attorney General Sally Yates - who was sacked by Trump after she refused to defend his travel ban - and former Director of National Intelligence James Clapper also testified in front of a Senate subcommittee on crime and terrorism on Monday.
Mr Trump tweeted on Friday: "James Comey better hope that there are no "tapes" of our conversations before he starts leaking to the press!"
"I'm not under investigation", Trump added.
"I think we ought to get to the bottom line here: President Trump is unsafe", Durbin told MSNBC, the cable news channel. Trump's visible anger and erratic tweets prompted a reporter to ask Spicer on Friday if the president was "out of control". He said the discussions happened in two phone calls and at a dinner in which Comey was asking to keep his job. "And as a effect, I was not aware of the counterintelligence investigation Director Comey first referred to during his testimony before the House Permanent Select Committee for Intelligence on the 20th of March, and that comports with my public statements". CNN said Comey is "not anxious about any tapes" Trump may have, citing an unnamed source familiar with the matter. In Clinton's case, the ostensible obstruction consisted exclusively in lying under oath about a sordid sexual affair that may have sullied the Oval Office but involved no abuse of presidential power as such.
Democrats and some Republicans have expressed concern at the timing of the probe, noting the FBI's current investigation into alleged interference by the Russian government in the us presidential election. On Thursday, Trump told NBC he knew he ran the risk that by firing Comey he would "confuse people" and "lengthen out the investigation" into ties to Russian Federation. Comey declined to make that promise but told the president he could count on his honesty, the paper said.
Despite the FBI, as well as Senate and House intelligence committees, conducting investigations into collusion between the Trump campaign and Russia, Mr Trump said it was a Democrat conspiracy.
The White House has said Comey's firing was unrelated to the Russian Federation probe, but in the interview with NBC News on Thursday, Trump said he knew he ran the risk that by firing Comey he would "confuse people" and "lengthen out the investigation" into ties to Russian Federation.
Trump's frustrations came to a head this week with the firing of FBI Director James Comey, who was overseeing the probe into his campaign's possible ties to Russia's election meddling.
Trump revealed to Holt that he had been planning to fire Comey even before he received Deputy Attorney General Rod Rosenstein's recommendation to do so.
The tax returns, the lawyers say, largely reflect income and interest paid by the web of corporate entities that made up The Trump Organisation prior to Mr Trump taking office.
He also defended the struggle by his administration to come up with a consistent timeline and rationale for the abrupt firing of FBI Director James Comey this week.
In doing so, though, Trump sought to criticize Comey after suddenly firing him earlier this week.
"You don't mean that", Pirro responded.
