Here’s a look at key health officials working with President Joe Biden and Vice President Kamala Harris.

Why include Representative Fudge (D–Ohio) in this roundup? As HIV and homelessness advocacy group Housing Works is fond of claiming, “Housing is health care!” Plus, in her HUD role, she’ll oversee the Housing Opportunities for Persons With AIDS program.
