LARGO, Maryland — At their first public event since turning over the top of the 2024 Democratic ticket, President Joe Biden took on an unfamiliar role of ceding the spotlight to Vice President Kamala Harris.

Supporters turned out in droves to Prince George’s Community College just outside of Washington, D.C., for the event, which was a White House shindig ostensibly to announce the 10 drugs selected for Medicare’s new price negotiation process that effectively doubled as a Harris campaign rally.
