Here's the tweet from Philip Crowley, U.S. Assistant Secretary of State for Public Affairs: The U.S. is conveying "support for orderly transition in Egypt." I haven't seen anything else to indicate that Mubarak's going. But there's a presidential address announced, so who knows? At WSJ, "Mubarak to Address Nation as Protests Mount."
And at Israel Matzav, "White House Has No Egyptian Strategy." Also, at The Other McCain, "‘The Euphoria Is Fading’."
Expect new updates and analysis later today ...
ADDED: At NYT, "Obama Urges Mubarak Not to Run Again."
