The intelligence disclosed by Mr Trump in a meeting with Sergey V. Lavrov, the Russian foreign minister, and Sergey I. Kislyak, the Russian ambassador to the United States, was about an Islamic State plot, according to the officials. The threat was related to the use of laptop computers on aircraft.
MILLER: That's right. And they try to reach - they call and make attempts to call the CIA director and the director of the NSA to basically give them a heads up that this had happened because those agencies are probably the most front-line, most engaged directly with this particular partner, this intelligence partner whose information Trump had exposed. They said it was considered so sensitive that details have been withheld from allies and tightly restricted even within the USA government.
National Security Adviser H.R. McMaster walks back to the West Wing of the White House in Washington, Monday, May 15, 2017, after speaking to the media.
"During that exchange the nature of specific threats was discussed, but they did not discuss sources, methods or military operations", he said.
He said Secretary of State Rex Tillerson and Dina Powell, deputy national security adviser for strategy, remember the meeting the same way. "The on-the-record accounts should outweigh those of anonymous sources".
Buzzfeed News corroborated the report Monday, citing two USA officials who had been briefed on Trump's meeting with Lavrov and Kislyak. Trump 'revealed more information to the Russian ambassador than we have shared with our own allies'. "And the president did not disclose any military operations that were not already publicly known".
According to a Reuters/Ipsos opinion poll released on Monday, a majority of Americans, including a growing number of Republicans, want to see an "independent investigation" to sort out any connections between Russian Federation and Trump during the 2016 election campaign.
Mr McMaster did not address that in naming the city, in Islamic State-controlled territory, Mr Trump gave Russian Federation an important clue about the source of the information.
Top Cabinet-level officials tried to contain the damage caused by the report, but their efforts were overwhelmed by questions about White House credibility, including discredited statements about the firing of Federal Bureau of Investigation director James Comey.
The CIA declined to comment to the Post while the NSA did not respond.
"If it is, it would be very troubling", Sen Lindsey Graham, R-S.C., a member of the Senate Intelligence Committee, said in an emailed response to a question.
The story prompted Sen.
In July a year ago he tweeted: "Crooked Hillary Clinton and her team 'were extremely careless in their handling of very sensitive, highly classified information.' Not fit!"
"Risking sources and methods is inexcusable, particularly with the Russians", Democrat Senator Mark Warner wrote on Twitter.
Talking to reporters, McMaster described the story as false.
Early responses to the bombshell report indicate that, if true, handling sensitive details in this manner would have broad implications on USA partnerships around the world and could place the lives of agents in the field at risk. "It could harm our national security by cutting off important sources of intelligence that protect Americans against terrorist acts".
For Trump's already tired allies in Congress, the latest crisis brought more headaches and demanded yet more explanation from an administration that is struggling to leave its legislative mark.
"The US White House explained that there was no scandal and it was posted on their website that that everything had been agreed like in the case with other ministers", Lavrov said.
A spokesman for House Speaker Paul Ryan said protecting secrets is paramount, and the speaker "hopes for a full explanation".
Senator Bob Corker, a prominent Republican and chairman of the Senate foreign relations committee, said the White House was in a "downward spiral" following the reports on Monday evening.
