On 4 July 2013, 68-year-old Chief Justice of the Supreme Constitutional Court of Egypt Adly Mansour was sworn in as acting president over the new government following the removal of Morsi. The new Egyptian authorities cracked down on the Muslim Brotherhood and its supporters, jailing thousands and forcefully dispersing pro-Morsi and/or pro-Brotherhood protests. Many of the Muslim Brotherhood leaders and activists have either been sentenced to death or life imprisonment in a series of mass trials.
