President Joe Biden was in California over the weekend for a glitzy campaign stop with former President Barack Obama and several high-profile celebrities, including George Clooney, Julia Roberts and Jimmy Kimmel.

Kimmel served as moderator for the discussion between Obama and his former vice president. The event raised a little over $30 million for Biden's reelection campaign, according to an official.
