Probably not true. Looks like disinformation against McMaster by Obama holdovers trying to delay their own departure.
“Let’s hope this is fake news. I cannot see Trump letting this happen.”
Unfortunately I can. Trump is FAR less pro active then I would have expected. I mean jeez Rosenstein is still there, the guy who engineered the Mueller witch hunt. He could have had someone in there to get Mueller under control but did nothing and it may cost him his Presidency.
Except that he isn't firing any of Obama's holdovers - why would they think they'll be fired?
