Supporters of Bernie Sanders disrupted the first day of the Democratic convention on Monday, repeatedly chanting and booing mentions of Hillary Clinton's name as the party's hopes for a show of unity dissolved into frequent chaos.

Speakers in the convention's first hours struggled to carry out business as angry Sanders supporters roared their disapproval, drawing a deafening response from Clinton delegates.

"We're all Democrats and we need to act like it," U.S. Rep. Marcia Fudge of Ohio, the convention's chairwoman, shouted over the uproar.
