Very simply, from the transcript of Chris Matthews’ closing on a Thursday night’s HARDBALL:

I guess when he gets mad, he can really excel at what he does.

“Tomorrow’s Friday. If the president were to rise at dawn and say, “It’s Saturday,” what would be the meaning of that statement? Would his people – those who back him no matter what – check their calendars and convince themselves the calendar they’ve been using is wrong and the leader they adore is right? … This whole thing about President Obama wiretapping Trump is nothing but trumped up nonsense …  The man in the White House is demonstrably capable of making up claims that have no reality. He’s no better than the weirdo in the basement who calls in the fire alarm just to hear the sirens go past.”
