The chief justice of Egypt's Supreme Constitutional Court judge Adly Mansour was sworn in Thursday as the nation's interim president, taking over hours after the military ousted President Mohammed Morsi. Morsi's successor took the oath of office at the Nile-side Constitutional Court in a ceremony broadcast live on state television. According to military decree, Mansour will serve as Egypt's interim leader until a new president is elected. A date for that vote has yet to be set. Mansour used his first remarks as interim leader to praise the massive street demonstrations that led to Morsi's ouster. He hailed the youth behind the protests that began on June 30 and brought out millions around the country.
