US President Donald Trump discussed specific terror threats with Russian Foreign Minister Sergei Lavrov and Moscow's envoy to the US in the Oval Office last week, but not "sources or methods," senior officials said Monday.
The statements from National Security Advisor HR McMaster and Secretary of State Rex Tillerson came after The Washington Post reported that Trump had revealed classified information to the Russians about a threat posed by the Islamic State group.
"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 any intelligence sources or methods discussed and no military operations were disclosed that were not already known publicly," he added, in a statement provided by the White House.
