Baltimore Mayor Opens DNC Amid Party Chair's Resignation

PHILADELPHIA (AP) -- Democrats have gaveled in their convention in Philadelphia -- after a day of discord that sent the party chief into exile.

It was Baltimore's mayor, Stephanie Rawlings-Blake, who called the 47th Democratic convention to order. Her formal welcome was briefly held up a slight oversight -- she forgot the gavel and had to retrieve it off stage.

Rawlings-Blake is a last-minute fill-in Debbie Wasserman Schultz, the ousted Democratic National Committee leader.

The Florida congresswoman was forced out of her post by a trove of leaked emails that appeared to show DNC officials favored Hillary Clinton over Sanders in their fierce primary fight. She's set to step down from the party job after the convention.

Rawlings-Blake serves as secretary of the DNC.
