"According to people familiar with Mr. Flynn’s visit to the intelligence
seminar, the source was alarmed by the general’s apparent closeness with
a Russian woman who was also in attendance. The concern was strong
enough that it prompted another person to pass on a warning to the
American authorities that Mr. Flynn could be compromised by Russian
intelligence, according to two people familiar with the matter."
Maybe Trump mooned someone when he was a kid or threw spitballs at his teacher. Perhaps Mueller can indict him for one of those.
Either Mueller and his team are the dumbest most incompetent investigators in the history of the universe, Trump's IQ is so fucking high that he easily outsmarted all of them or there is no Russian collusion!
