Let us be clear: we don't think Trump is guilty of diddly-squat, nor do we think he's a liar in the (ahem) traditional sense of the word. That being said, we believe the likelihood of his committing perjury under oath to be way over 100%.
This is owing to Trump's unique tendency to believe that anything which comes out of his mouth is true, no matter whether or not it intersects with "reality" in any way.
Take, for one of a million examples, his assertion that he "watched in Jersey City, N.J., where thousands and thousands of people were cheering as the World Trade Center collapsed (on 9/11)." We have no doubt that Trump is telling the truth as he remembers it...but it never happened.
Or more recently when he threatened James Comey with his super-secret White House recordings of private conversations between the two men...which subsequently proved not to exist.
Trump is a showman, a raconteur, a salesman, a serial embellisher, and the owner of a Tourette's style mouth which blurts out anything - and we mean anything - that flits through his mind. We're not even sure his brain is telling his mouth what to say, or whether his brain just likes to listen to his mouth as if it were a favorite talk radio station.
Considering the mounting evidence that the whole Comey/Mueller/FBI/Russia circus was intended to do nothing other than frame Trump and throw him out of office, we think having him say anything under oath is likely to go badly indeed.
Still, if he does go through with this, we'd like to make two suggestions. First, the President should remember that the words "to the best of my recollection" are his new best friends.
And second, at the same session, put Mueller under oath too and let Trump ask him questions about why he chose anti-American conspiracists for his so-called investigative team.
