Secretary of State Rex Tillerson said in a statement earlier Monday that Trump discussed a "broad range of subjects" with Russian Foreign Minister Sergey Lavrov and Russian ambassador to the US Sergey Kislyak.
Democratic senators blasted President Donald Trump Monday, saying they are shocked and concerned amid reports he revealed highly classified information to the Russian ambassador and foreign minister. The Post did not claim sources, methods or military operations were discussed, but that Trump mentioned classified intelligence from a sensitive source. An official also said that Trump revealed the city in the Islamic State's territory where the USA intelligence partner detected the threat.
House Minority Leader Nancy Pelosi, D-Calif., said in a statement that Congress "must be given a full briefing on the extent of the damage President Trump has done in compromising highly classified code-word intelligence to the Russians".
National Security Adviser H.R. McMaster told reporters outside the White House that the "story that came out tonight, as reported, is false".
"The president and the foreign minister reviewed common threats from terrorist organizations to include threats to aviation", said McMaster who participated in the meeting.
"At no time were intelligence sources or methods discussed and the president did not disclose any military operations that weren't already publicly known", he said during the White House press conference.
The freakish scenes Monday night included a surprise encounter between reporters and Trump's top national security adviser and an attempt to drown out possible conversations with a blaring television. Their on-the-record accounts should outweigh those of anonymous sources.
McMaster says that "at no time were intelligence sources or methods discussed".
Trump reportedly even revealed the city in which the intelligence was gathered - something seen as problematic, as it could allow Moscow to identify the partner nation.
The story will only heighten Trump's strained relations with intelligence workers and former officials, who have expressed worry about sharing classified information with a former NY business magnate who often shoots from the hip.
The reports comes as federal officials continue an ongoing investigation into Russia's meddling in the 2016 election, which saw Trump winning the Electoral College vote.
"The second damage is that third countries who provide the United States with intelligence information will now have pause to do so if the United States is sharing such information with the Russians without their permission", Morell said in a conversation with CBS News' Scott Pelley. The officials said Trump's revelations endangered the cooperation with the USA ally who is reported to have access to the workings of the Islamic State.
"Effectively, Trump's actions have thrown world's most important intel sharing relationship into doubt at best, serious jeopardy at worst", Stephanie Carvin, a former national security analyst for the Canadian government, said on Twitter, referring to the "Five Eyes" arrangement.

Sen. Lindsey Graham (R-SC) could only muster up enough courage to tell a reporter the report would be "troubling" if it was true.
Monday's reports of Trump revealing classified information to the Russians come just ahead of his first foreign trip as president.
Sen. Mark Warner, D-Virginia, called the situation "a slap in the face to the intel community" and Sen.
"Even if President Trump unwittingly blew a highly classified code-word source to the Russians, that would be unsafe enough", Pelosi said.
Congressional Republicans and Democrats expressed concern about the report.
Republican Susan Collins, a ME senator, put her party's apparent exasperation more concisely in a light-hearted aside comment to reporters. "The speaker hopes for a full explanation of the facts from the administration".
Sen. Jim Risch (R-ID) was even more defensive, noting, "It's no longer classified the minute he utters it", a response that dismisses the consequences of revealing secret information to Russian Federation, as well as betraying the confidence of the ally who gave it to us. The chairman of the Senate foreign relations committee, Republican Bob Corker, said that the White House is spiraling out of control. "There's lots we don't know", he said.
"The shame of it is there's a really good national security team in place and there are good, productive things that are under way through them and through others", Corker said.
