Former U.S. presidential candidate Hillary Clinton endorsed fellow Democrat Joe Biden's campaign for the office she once sought on Tuesday.
"This is a moment that we need a leader, a president like Joe Biden," she said during a joint event online with the former vice president.
The endorsement, while no surprise, marks the latest in a series of high-profile Democrats lining up behind Biden ahead of what is expected to be a tight Nov. 3 election rematch between their party and Republican President Donald Trump.
