not necessarily done anything illegal or unethical but i think he has some serious questions to answ answer. >> now, the president, i argue, made a problem for himself and his lawyer when he said "i don't know what rudy was doing over there, you have to ask him." not only is that a problem for rudy because rudy's supposed to be acting in the interest of his client, that's his ethical obligation. so if the president didn't know what he was doing when rude see says he did, that's a problem if that comes to pass. but secondarily, we know from the telephone call, from sondland, from the collective conscience from people o testified that the president knew very well what rudy was doing there because he was the one who wanted him to do it. >> i can't speak for the president, i think the optics are very bad. >> do you think the president didn't know what ephs going on when he said to the ukrainian president "talk to rudy"? >> i don't know what that comment meant.
