"I don't think he's that stupid ( in this specific regard ) to have been involved."

I'm not sure if he's that stupid, but his entire existence is ego generated, and I believe, his ego pretty much dictates everything he says and does. I truly believe he is mentally unstable. Whether or not he was actually "hands on" involved with the Russian hack I of course don't know, it certainly wouldn't surprise me, but there is absolutely no doubt in my mind that he knew about it and more than likely at least encouraged it. It's going to be very interesting to see if he can pivot his way out of this one. As for as lying to Congress, it pretty much goes without saying that he will lie to whomever he happens to be talking to at the moment and he won't segregate Congress in that manner. For him to tell the truth he would more than likely incriminate himself. As you said, we will see. Stock up on the popcorn.
