President Trump shared highly classified information with Russian government officials during an Oval Office meeting last week, according to a report published Monday evening.

Trump informed Russian Foreign Minister Sergei Lavrov and Russian Ambassador Sergey Kislyak about the Islamic State's intentions of carrying out a terrorist attack on an airplane by using a laptop computer.

Trump "revealed more information to the Russian ambassador than we have shared with our own allies," one government official said.

The information was not U.S. intelligence to share, potentially risking this source for ISIS intel in the future. The ally had not given permission to share the information with Russia.

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