A-List Democrats Make Case for Clinton as Sanders Delegates Hedge

Bernie Sanders' supporters erupted in boos and chants almost from the moment the Democratic convention was called to order Monday, ignoring pleas from their candidate to avoid protests and threatening to undo the carefully crafted display of unity that Hillary Clinton's campaign had plotted for her formal nomination.

Representatives from the Clinton and Sanders campaign held an urgent meeting Monday afternoon to come up with a plan to avoid disruptions as it became clear that the removal of Democratic National Committee Chair Debbie Wasserman Schultz after e-mails emerged showing the DNC had favored Clinton during the primary campaign hadn't doused the anger of the Vermont senator's supporters, according to a party official.
