Sanders backers revolt on raucous opening day at U.S. Democratic convention

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," US Representative Marcia Fudge of Ohio, the convention's chairwoman, shouted over the uproar.
