We know Michael Cohen is a liar, he either lied to Congress or he is lying now.
The question is, why does Mueller believe the current version of the story?
Unless Mueller is an Idiot, (he is not) he believes the current version because Michael Cohen was able to provide some corroborating evidence. If Mueller has strong evidence, RUMP is busted. If Cohen's current story is true, Rump's goose is cooked.
Run Trumplicans, Run.
