transition, Vice President Omar Suleiman.

"There are forces in at work in any society," Clinton said, "in particular in one that is facing these kinds of challenges, who will try to derail or overtake the process to pursue their own specific agenda, which is why I think it's important to support the transition process announced by the Egyptian government actually headed by now-Vice President Omar Suleiman."
