U.S. Speaker of the House Of Representatives Nancy Pelosi has endorsed Joe Biden for president, joining a list of top Democrats who have recently thrown their support behind the former vice-president. Pelosi’s endorsement of the Democratic presidential candidate follows that of U.S. Senators Elizabeth Warren and Bernie Sanders, former president Barack Obama and former vice president Al Gore, who all threw their weight behind Biden earlier this month.
