President Trump did not know where the information about an ISIS terror threat to jetliners he shared with Russian officials came from or how it was obtained, his national security adviser said Tuesday.

“I should just make maybe the statement here that the president wasn’t even aware where this information came from. He wasn’t briefed on the source or method of the information either,” said H.R. McMaster, a US Army general who was in the Oval Office meeting last week with Trump and Russia’s ambassador and foreign minister.

McMaster, who would not say whether the information Trump shared was classified, offered a broad defense of the president during a White House press briefing.

He also slammed the Washington Post, which first reported the story.

“What I’m saying is the premise of that article is false that in any way the president had a conversation that was inappropriate or that resulted in any kind of lapse in national security,” he said before targeting White House leaks.

“I think the real issue, and I think what I’d like to see really debated more, is that our national security has been put at risk by those violating confidentiality and those releasing information to the press,” McMaster said.
