Bernie Sanders has endorsed Joe Biden’s campaign to take on Donald Trump in November’s election.
Senator Sanders pulled out of the contest to be the Democratic Party’s nominee last week, leaving Mr Biden as the only remaining candidate.
In a live split-screen webcast, former vice-president Mr Biden thanked his former rival for the endorsement.
Senator Sanders urged all Americans to unite to defeat Mr Trump.
He described him as “the most dangerous president in the modern history of this country”. (Text courtesy BBC)
