>> chris, one of the issues here is that if he now has his eye on firing rod rosenstein which apparently he does, that's almost a bigger challenge than firing mueller because the deputy attorney general so long as jeff sessions is there has the ability to curtail this investigation. and i think that's what we should keep our eye on. he fires rosenstein, then he can put in whoever and that person can say you're not going to look at michael cohen, you're not going to look at all of these business deals. all you're going to look for is direct evidence of collusion. if trump didn't pick up the phone and call putin, i guess we're done with that. that is something congress had better be wise, too. if anybody's interested in doing any oversight, call mr. rosenstein up to testify, ask him whether the president has the authority to fire mr. mueller directly.
