Outgoing Democratic National Committee chair Debbie Wasserman Schultz was booed and jeered at a pre-convention delegation breakfast this morning in Philadelphia, a day after the Democratic National Committee chair announced she would resign from the post following the leak of embarrassing party emails. Amid ugly scenes, an event organizer repeatedly tried to quiet the crowd, but the boos continued as Wasserman Schultz began speaking. "Shame on you!" screamed some. "You rigged the election!" was another repeated refrain. Many of the vocal protesters were seen wearing shirts supporting Sen. Bernie Sanders.
