Update 5:34 p.m. ET: President Barack Obama will speak about the turmoil in Egypt this evening, the White House said.
A senior U.S. official tells NBC News' Andrea Mitchell that Egyptian President Hosni Mubarak's speech today has put President Barack Obama in a tough spot:
The official said Mubarak didn't go far enough when he promised not to seek re-election in September but said he intended to serve out his term. The protest movement is likely to intensify, not dissipate, the official said.
"The reality is he has moved," the official said, but "it is not enough."
"There are a few steps more in this process," the official said. "It may take a few more days."
For Obama, the problem is that if he pushes too hard, he will not only antagonize other leaders in the region but will also be seen as ignoring Mubarak's legitimate accomplishments during 30 of rule. "He was the first Arab leader to embrace the new Iraq," the official said. "He has had a profound effect on the peace process.
"How you recognize his contributions while also paving the way for fundamental change?" the official asked. "That is hard."
U.S. officials say the significant factor is the outreach the army has done to the Egyptian people by positioning themselves as protectors — the sign of a professional army that is tied to the state, not to the leader.
