Well this is interesting. The White House counsel, McGahn, has cooperated with the Mueller investigation, giving them 30 hours worth of interviews. He told them under oath that he saw no illegal actions by the President. Mind you this isn't Trump's personal lawyer but the White House counsel. His first duty is to protect the presidency. Newt Gingrich just pointed out Mueller made a fatal error. He got the White House counsel to vouch for the President under oath. The report about the cooperation came out in the New York Times this weekend. According to Gingrich there is now no legal reason for Trump to be questioned. Trump had signed off on McGahn cooperating so I suspect a chess master thought quite a few moves ahead. Gingrich said Mueller might as well write his report and go home. Mueller will have to stand up in court and show evidence that contradicts a very well respected government lawyer. Doubtful McGahn perjured himself under oath.
