The information came from a key US intelligence source on the so-called "Islamic State" (IS) terrorist group who had not given the administration permission to share the material with Moscow.
During Lavrov and KisylakÎ„s visit to the Oval Office on May 10, Trump allegedly went off-script and offered details related to an IS terror plan involving laptops on airplanes, the Post reported. According to anonymous officials, the information sharing jeopardizes a highly-sensitive intelligence partnership that has given the US privileged insight into the internal organization of IS.
Trump "revealed more information to the Russian ambassador than we have shared with our own allies," the Post quoted a former US official close to the matter as having said. The information was reportedly of such a sensitive nature that its details were withheld even within the ranks of the US government.
After the White House meeting, administration officials placed calls to the CIA and the National Security Agency (NSA) in an attempt to limit the damage done, the Post wrote.
The paper also noted it was withholding the terror plot details at the advice of officials to prevent risking intelligence capabilities. In recent days, the US has mulled over expanding a ban on laptops in airline passenger cabins to include flights originating in Europe.
White House disputes report
National Security Adviser H.R. McMaster, who was present at last weekÎ„s meeting, has disputed the paperÎ„s account, denying that any "sources or methods" were discussed in the closed-door conversation.
"The president and the foreign minister reviewed common threats from terrorist organizations to include threats to aviation," McMaster said. "At no time were any intelligence sources or methods discussed, and no military operations were disclosed that were not already known publicly."
Because the president has wide authority to declassify government secrets, TrumpÎ„s alleged revelations of government secrets to an adversary do not likely break the law. However, unnamed sources in the report described TrumpÎ„s behavior as "reckless," and they questioned his ability to understand political consequences.
Divulging information on an IS intelligence-gathering partner to Russia is problematic as Moscow backs President Bashar al-Assad, whereas the US supports anti-Assad rebels. Russia could use the divulged details to identify WashingtonÎ„s intelligence partner on the ground and possibly disrupt the sourceÎ„s intelligence-gathering capabilities. Î„Slap in the faceÎ„ The meeting between Trump and the Russian officials came just one day after Trump fired FBI Director James Comey, who had been heading up an agency probe into possible links between Moscow and TrumpÎ„s campaign team.
ComeyÎ„s sudden dismissal unleashed reprimands from across the political spectrum, and MondayÎ„s report once again quickly drew sharp criticism of the US president. Mark Warner, a senator from Virginia and the top Democrat on the Senate Intelligence Committee, said that should the report prove true, it would be a "slap in the face" to American intelligence agencies. Democratic Senator from Illinois Dick Durbin called for an investigation into the matter. Republicans have also expressed their concern over the report, though they emphasized it had yet to be proved. Senator John McCain of Arizona tweeted he would find it "deeply disturbing" should the allegations prove to be true. Republican Bob Corker, head of the Senate Foreign Relations Committee, similarly described the PostÎ„s report as "very, very troubling" if true.
