Video: Republicans speak out against Susan Rice

>> right out on the senate floor and shot right back at the president. nbc's kelly o'donnell has more for us.

>> reporter: good evening, brian, this is really the latest chapter in what is a contentious history between the president and john mccain . and so after the news conference, john mccain went to the senate floor for his own televised rebuttal, taking on the president and the future of ambassador rice.

>> if the president thinks that we are picking on people, he really does not have any idea of how serious this issue is.

>> reporter: serious enough that some republican senators stepped forward after the president's news conference, repeating their vow to stop president obama from nominating u.s. ambassador rice from becoming the next secretary of state.

>> she has says this was not a pre-planned attack, why was that done?

>> reporter: for weeks, the republicans have expressed their anger with rice, urging her to explain the appearances regarding the video and the protest over benghazi .

>> this is in response to a hateful video.

>> i have grave concerns. i would need to have some clearances from ambassador rice before i could support her for any position

>> this president and this administration has either been guilty of colossal incompetent works or engaged in a cover-up, neither of which are acceptable to the american people .

>> reporter: also today, mueller and joyce briefed the top commanders on the scandal involving petraeus. the acting cia director was also here for private meetings, and the big expectation tonight is that petraeus himself will come forward to testify about the benghazi attack, not his own troubles, as early as tomorrow or friday troubles, as early as tomorrow or friday. now there now there are some differences among republicans about what is the best way to get to the bottom of what happened in benghazi , some say the current investigations are sufficient. but john mccain and others are calling for a watergate style select committee with broader authority to investigate.
