Amr Moussa says he expects Mubarak to remain in his post until his term ends in seven months, though "there are extraordinary things happening and there is chaos, maybe he will make a different decision."

Moussa says he believes it would be impossible to organize new elections quickly.

He also says he would consider a role in a transitional government. Asked about a potential run for the presidency, he responded, "why say no?"

Moussa spoke to France's Europe 1 radio on Friday. He also said any new government in Egypt "cannot ignore the Muslim Brotherhood," the country's largest opposition group.
