This is exactly what makes the President of the Electoral College a liar. One can state their opinion and not be considered as such, but once you have the research or information regarding any specific subject and continue to state the opposite as to support your own position or mislead a constituency, you are indeed a LIAR. A lie is an intentionally false statement. This weak individual is intentionally pushing his propaganda for ratings, for continued distraction of what's going on within his administration and the resistance movement that's itching for press coverage, and ultimately for perpetual feeding of his Id. THE MAN IS A PATHOLOGICAL LIAR. 

In regard to Trump being a fool... I certainly wouldn't make that assumption. He made it to the White House, didn't he? He's doing a very fine job of gaslighting the public (mostly, his supporters), which would make him no fool but rather a quite powerful man. Just look up the definition of Gaslighting. It's DT to a t.
