Lady Gaga was also among the celebs on hand. Earlier in the event she performed “God Bless America,” and after Harris delivered her rousing get-out-the-vote pitch, she returned to the stage for a surprise performance of her classic, “The Edge of Glory.

As she did with her Super Bowl performance, she delivered her rendition of "God Bless America" as a staunch act of patriotism in a time of need.
