resignation

AP - The Obama administration is in talks with top Egyptian officials about the possible immediate resignation of President Hosni Mubarak and the formation of an interim government that could prepare the country for free and fair elections later this year, U.S. officials said late Thursday.

President Obama's chief of staff Rahm Emanuel is stepping down, and the president's senior adviser, Pete Rouse, is stepping into the role until a permanent replacement is named.

The resignation has been expected for days, but Obama made it official Friday with an announcement at the White House.

Naming the replacement could have implications for the upcoming midterm elections.

The activist investor cuts his stake by tens of millions of shares in the months following his resignation from Yahoo's board last fall.

The business software maker announces the resignation, effective immediately, and the appointment of co-CEOs to replace Apotheker.

The election Monday follows last month's resignation of Michael Martin, who became the first speaker in more than 300 years to step down.

Martin took the fall after details were leaked to a national newspaper of a parliamentary expenses system that allowed MPs to claim an array of goods and services at taxpayers' expense.

The resignation of the state's science curriculum director last month has signaled the beginning of what is shaping up to be a contentious and politically charged revision of the science curriculum, set to begin in earnest in January.
