Barack Obama is lending Joe Biden his Democratic star power for the first time in the hope of enticing support and small-dollar donations as Democrats try to catch up to Republican fundraising.

The Biden campaign has gleefully touted the virtual event, slated for Tuesday night, since it was announced last week to much fanfare. Along with the Democratic National Committee, the Biden team is also heavily promoting a separate, exclusive meet-and-greet with the former president before the main gathering through a flurry of text messages, emails, and social media posts.
