Comey can't seem to leave out of the public eye nowadays. This might be a distraction to hold peoples attention and create political drama for the masses. The hearing is to try to find out what he and trump spoke of. A foreign adversary attack home to destroy public faith in our voting process here in the United states. I'm not sure what our elections have to do with the Russians. These dudes might be talking about Russia Today which is a great show. The President fired Comey because of his involvement with the Russian investigation and now he is testifying.
Under oath he agrees to tell the truth and nothing but the truth. When he was appointed in 2013, he knew he could be fired for any or whatever reason. The shifting explanations confused him as the president told him he was doing a great job. He was dumbfounded as to why he was fired. He felt defamed by the media saying that the FBI was in disarray and disorder. He reaffirms that this was a lie. He believes in the mission of the FBI to "protect" the American people. He thanked and apologized to the FBI in his introductory statement.
He did not see any altering of any votes. He felt the need to document any meetings with President trump. His common sense told him that Mr.Trump wasn't a very trustworthy. He felt uneasy when the President was asking him for his unfettered faithfulness. The intention of this testimony seems to be to demonize Russia and blame them for cyber attacks. The way I see this, the testimony means nothing and solves nothing for the American people. The waste of time is serious with this one.
