UPDATE: In a press conference moments ago, White House Press Secretary Robert Gibbs was unable to say whether or not Obama stands by Egyptian President Hosni Mubarak.
Protestors have now come out in thousands in the Egyptian capitol, Cairo, inspired by protestors' apparent recent success in bringing an end to the nearby regime of Tunisian President Ben Ali. In Egypt, protestors are calling for a similar end to the reign of Western-ally President Hosni Mubarak.
