unrest in egypt. earlier, i sat down with john roberts who is in for chris wallace on "fox news sunday." so much uncertain in egypt today. hutwo key guests from the senate to talk about the u.s. role -- should we have one? >> senator corker and senator reid. the one thing that is certain about egypt is the amount of uncertainty. beyond that, it's anybody's guess. they could name a new prime minister to take over without one of the parties who was supportive of morsi going, saying, no, we are not going to work with this guy. you have to pick somebody else. senators corker and reid both said the u.s. should be a calming influence over the region. now, they may be able to do that in terms of the egyptian military because we give them an awful lot of money. but there is a free for all between the anti-morsity and pro-morsi forces and how do you inject any kind of calming influence, particularly on the morsi side and islamic militants
