President Trump revealed highly classified information about Islamic State militants to Russian officials during a meeting at the White House last week, the Washington Post reported Monday.
The newspaper cited current and former U.S. officials who said Trump shared details about an Islamic State terror threat with Russian Foreign Minister Sergei Lavrov and Russian Ambassador Sergey Kislyak. The threat was related to the use of laptop computers on aircraft.
National Security Adviser H.R. McMaster told reporters outside the White House that the "story that came out tonight as reported is false."
"At no time were intelligence sources or methods discussed, and the president did not disclose any military operation that were not already publicly known," McMaster said. However, the Post story and other subsequent reports didn't say that it was sources, methods or military operations discussed, but simply classified information.
