>> interesting development. covering the justice department for us. might he at some point, rosenstein, feel compelled to recuse himself. he said publicly would he if necessary. >> i think, look, i think that possibility is very much on his mind. and i think, you know, partly you saw from the tweet today which by the way came as surprise by the president's own legal team. they didn't expect him to be up and tweeting and certainly not the attack on the deputy attorney general. but i think rosenstein's thought is that if it comes to that, and if he becomes a witness, in this investigation, that is now run by robert mueller, special coins e counsel, then that need may arise. today we are are told again by justice officials that that is still the state of play. and obviously inside the justice department there's a lot of tension built around this whole idea, you know, you have a bit of tension between the deputy attorney general on the forth floor and fifth floor of the attorney general, two of them are not really seeing eye to eye
