Former President Barack Obama is returning to the campaign trail for Vice President Kamala Harris, using his popularity among Democrats to host a high-dollar fundraiser for her on Friday in Los Angeles.

The fundraiser marks Obama’s political return to the City of Angels months after he hosted a similar event there for President Joe Biden. A recording of Obama helping Biden off the stage after it, in addition to co-host actor George Clooney’s op-ed following Biden’s debate against former President Donald Trump, contributed to the pressure campaign mounted on the incumbent to step down.
