allegation. so i think the president has one of two choices. either retract or to provide the information that the american people deserve because if his predecessor violated the law, president trump violated the law, we've got a serious issue here, to say the least. i have no reason to believe that the charge is true, but i also believe that the president of the united states could clear this up in a minute. all he has to do is pick up the phone, call the director of the cia, director of national intelligence and say, okay, what happened? because they certainly should know whether the former president of the united states was wiretapping trump towers. >> all right, so let's discuss this with cnn law enforcement who is also a secret service agent. steve hall who is a retired cia chief of russian operations and cnn intelligence and security analyst bob behr. bob, let me begin with you.
