The big headline right now:
Trump revealed highly classified information to Russian foreign minister and ambassador – Washington Post
I’m not linking it because the WashPo is a purveyor of fake news. Obviously you can find it if you’re interested in giving them their click. This story is an intentional leak on the part of the President.
There were a limited number of people in the room. McMaster went to the WashPo and acted the part of the white knight stating that no such thing happened to throw Trump off the scent.
McMaster is a leaker. He will be gone soon.
