As many as 3,60,000 people have signed up to volunteer in support of Vice President Kamala Harris, her campaign has said, reflecting the groundswell of support in her favour in her race against former president Donald Trump.

Harris is the presumptive presidential nominee of the Democratic Party. She officially declared her candidacy for president last week after incumbent President Joe Biden withdrew from the race for a second term. She is expected to be officially declared as the presidential candidate by the Democrats at the party’s national convention in Chicago next month.
