President Donald Trump revealed confidential information to Russian Foreign Minister Sergei Lavrov and Russian Ambassador to the U.S. Sergey Kislyak during a White House meeting last week, according to a new report.

The information came from a U.S. ally and discussed the inner workings of the Islamic State, the Washington Post reported Monday.

The ally in question relayed the information, allegedly details about an ISIS terror plot, as part of an intelligence-sharing agreement; however, the ally had not approved the sharing of any information with Russia.

A U.S. official with knowledge of the situation told the Post that Trump had "revealed more information to the Russian ambassador than we have shared with our own allies."

Trump reportedly shared the information while discussing the high quality of intelligence that he regularly receives. The classified information was apparently prefaced by Trump telling Lavrov, "I get great intel. I have people brief me on great intel every day."

Senior White House officials informed the National Security Agency and the Central Intelligence Agency in an attempt to contain any damage caused by the information sharing, according to the Post.

National Security Adviser H.R. McMaster denied any sources or methods were shared with either Russian official.

"The president and the foreign minister reviewed common threats from terrorist organizations to include threats to aviation. At no time were any intelligence sources or methods discussed and no military operations were disclosed that were not already known publicly," McMaster said.
