On Sept. 11, 2012, the U.S. diplomatic post in Benghazi, Libya, was attacked. Four Americans died, including Ambassador Christopher Stevens. In the days and months following the deadly attack, the Obama administration has been criticized by Republicans for its handling of the tragedy. U.N. Ambassador Susan Rice withdrew her name from consideration for Secretary of State, and former Secretary of State Hillary Clinton testified before Congress. But Republicans have continued to press the issue, saying the White House misled the American people. The administration denies any wrongdoing. Diane and guests discuss the ongoing controversy over the Benghazi tragedy.
