The massive crowd gathered in front of the Philadelphia Museum of Art’s Rocky steps on Monday night had many hours to wait between before the evening’s headliner — Vice President Kamala Harris — finally took the stage.

VP Harris's campaign hosts a star-studded election eve rally in Philadelphia with Lady Gaga, The Roots, and more.

The lineup for the star-studded Philadelphia rally had been under wraps and was announced Monday as part of a series of rallies happening in seven battleground states.
