As the White House scrambled to mitigate the fallout from the report, which drew criticism from both sides of the aisle, National security adviser H.R. McMaster said on Tuesday that Trump's behavior at last week's meeting was "wholly appropriate". But when asked by a reporter on Tuesday whether Trump revealed the city from which the ISIS plot was detected, McMaster replied that what Trump discussed with the Russians about the Islamic State "was nothing you would not know from open-source reporting".
When Trump fired Comey, he said he did so based on Comey's very public handling of the Hillary Clinton email probe and how it affected his leadership of the Federal Bureau of Investigation. "Their on-the-record accounts should outweigh those of anonymous sources" in the news report, he said.
The panel's top Democrat, Elijah Cummings of Maryland, a constant Trump critic, called the allegation of Trump pressure on Comey "explosive" and said "it appears like a textbook case of criminal obstruction of justice".
McMaster added that Trump made a spur-of-the-moment decision to share the information in the context of the conversation he was having with the Russian officials.
Powell said: "This story is false". That could shatter trust that is essential to intelligence and counterterrorism cooperation.
The continuous flow of US intelligence leaks for publication by major media that appear to be targeting President Donald Trump and his administration are risking national security, current and former USA officials say.
The meeting came a day after Mr Trump fired his Federal Bureau of Investigation chief, James Comey, sparking criticism that he had done so because the FBI was investigating his election campaign's alleged Russian ties. Trump's first national security adviser, Michael Flynn, was sacked after he misled Vice President Mike Pence about conversations he had with Kisylak.
It's unlikely that Trump has broken any law.
Stewart is Utah's lone member of the House Intelligence Committee that is probing ties between Russian Federation and Trump associates after the country's meddling in the USA presidential election previous year.
The Post said the intelligence partner had not given the United States permission to share the material with Russian officials.
The revelation that President Donald Trump reportedly disclosed highly sensitive information to Russian officials is raising questions among some allied intelligence agencies about the security of details they share with their U.S. counterparts.
The CIA and the Office of the Director of National Intelligence declined to comment Monday evening.
Republican Rep. Robert Pittenger of Charlotte could not immediately be reached.
Aides in the White House were "furious" after photos from the meeting were tweeted by the Russian embassy in the United States even before the White House told reporters that Kislyak, the ambassador who is well known as a Russian spy, was in the meeting.
Should the intelligence communities have people on the ground - say they've penetrated the ISIS command structure or Kim Jong Un's inner circle - "Trump may have just burned them", Anderson said. Joe Manchin of West Virginia said he doesn't even tell his own staff and colleagues things he hears on the Senate intelligence committee. Such sharing "could be a risk for our sources", the official said. "That's the problem with the Russians - they lie". "He wasn't briefed on the sources and methods".
The story prompted Sen.
Trump's national security adviser also insisted Tuesday the story was no big deal.
"These reports, if true, are of the gravest possible concern".
Trump later was informed that he had broken protocol and White House officials placed calls to the National Security Agency and the CIA looking to minimize any damage.
