President Barack Obama will make a statement on Egypt at 1:30 p.m. EST, a few hours after it was announced on Egyptian state television that President Hosni Mubarak was announcing he would resign, the White House said Friday.

President Barack Obama said late Thursday it was not yet clear how Egypt's government is moving to transfer authority, on the same day when Mubarak said he would be handing some of his powers to his vice president but would remain in office until September's elections.

Obama said that while the Egyptian people had been told there was a transition of authority it is not yet clear that this transition is immediate, meaningful or sufficient.

The voices of the Egyptian people must be heard, Obama said. He urged the government to explain what changes had been made so far and lauded those who had assembled peacefully.

Obama urged the Egyptian government on Thursday to spell out in clear and unambiguous language the step by step process that will lead to democracy and the representative government that the Egyptian people seek.
