Hosni Mubarak continues to insist that he can't resign immediately, but the Obama administration is in negotiations with other Egyptian officials to have him to do just that, reports the New York Times. The leading possibility would be to have new VP Omar Suleiman, previously the head of intelligence, take control of a transitional government with the blessing of the military.
The transitional government would include representatives of the opposition, including the Muslim Brotherhood, say US officials and Arab diplomats. It's one of several options being discussed with high-ranking Egyptian officials, though not with Mubarak himself. Much remains in flux, with no guarantee that demonstrators—or even Suleiman—would go along. (More Egypt protests stories.)
