If Mueller says Manifort is lying then no doubt he is telling the truth. Mueller obviously wants someone to lie about the Trump Tower meeting because the truth is that it was a nothingbuger. Clinton’s people tried to set Trump up and failed. There was no collusion and thus no need for Mueller. He knew this going in. He was in on the frame.
He’s only there to protect the Clinton machine and try and run out the clock.
“If Mueller says Manifort is lying then no doubt he is telling the truth.”
Most likely, Manafort is refusing to lie for Mueller. Just like Corsi.
