CAIRO - In his first public speech addressing tens of thousands of mostly Islamist supporters, Egypt's president-elect Mohammed Morsi has vowed to free the blind sheik jailed in the U.S. for a plot to blow up New York City landmarks. Morsi, Egypt's first Islamist and civilian president-elect, promised Friday to work to free Omar Abdel-Rahman, the spiritual leader of men convicted in the 1993 World Trade Center bombing. He also promised to free detained Egyptian protesters facing military tribunals.
