Mueller is trolling for someone who will perjure themselves in order to file charges against Trump while covering up his own involvement in Uranium 1.
His leaking of grand jury indictments is illegal and unethical. Congressman Trey Gowdy has said as much this morning. So now it's looking like we're going to have to have a special counsel to investigate the special counsel. This "Trump Russia collusion" is becoming more absurd by the day.
