President Mohamed Morsi of Egypt has rejected the Egyptian Military’s ultimatum to respond to protesters within 48 hours or face a “political transition.” Morsi said he would be pursuing his own plan to deal with the historic demonstrations.

President Mohamed Morsi rebuffed an army ultimatum to force a resolution to Egypt’s political crisis, saying on Tuesday that he had not been consulted and would pursue his own plans for national reconciliation. But the Islamist leader looked increasingly isolated, with ministers resigning, the liberal opposition refusing to talk to him and the armed forces, backed by millions of protesters in the street, giving him until Wednesday to agree to share power.

Newspapers across the political spectrum saw the army’s 48-hour deadline as a turning point. “Last 48 hours of Muslim Brotherhood rule,” the opposition daily El Watan declared. “Egypt awaits the army,” said the state-owned El Akhbar.

The Obama Administration, whose lack of support for former President Hosni Mubarak was seen as critical in helping bring him down, disclosed that President Obama had told Morsi to be “responsive” to protesters.

President Obama on Tuesday called Egyptian President Mohamed Morsi, urging him to be “responsive” to anti-government protesters, amid growing political unrest and threats from Egypt’s military to assume power…

The White House said Obama urged Morsi “to take steps to show that he is responsive to their concerns, and underscored that the current crisis can only be resolved through a political process.”

It is hard to exaggerate how huge these protests are. By some accounts as many as 14 million protesters were in the streets of Egypt. In the wake of the protests multiple cabinet ministers have resigned from Morsi’s government including the foreign minister.

What remains of the Morsi Administration will have to deal with whatever happens when the time limit on the Egyptian Military’s ultimatum expires.
