IF it was "obstruction" it would be leaked by now. Same with "Russian Collusion"lain: He ADMITTED to Lester Holt that he believed if Comey was gone the investigation would be over. Rather than mimic Trump with his "alternate facts", why not just answer my previous question?
INTERFERING with an investigation is obstruction. For someone who insists there is no collusion with Russia, he continues to be paranoid over the fact that all of these investigations continue.
