The misinformation is what rolling you - believe it and you are a tool for the anti-trumpters who are trying to thwart Trump.
I trust Trump, he knows McMaster far better than you.
All reports are that Trump hired McMaster after a half-hour interview and that McMaster has rubbed him the wrong way—of course while being insubordinate in various ways too—ever since.
None of this stuff comes from the anti-Trumpers and the fervid defense of McMaster comes from Democrats and Never Trumpers. You just keep posting that down is up without evidence—because the evidence is all in the other direction.
