“Incredible performance from my friend Lady Gaga. You amaze me — and not just onstage. Proud to work with you to end sexual assault. #ItsOnUs,” Biden tweeted.

Lady Gaga headlined the Super Bowl’s halftime show Sunday night. Her performance did not include any obvious political statements, despite some speculation ahead of the show that the outspoken critic of President Trump would use her platform to get political. 

Biden and Lady Gaga collaborated on efforts to end sexual assault on college campuses while he served as vice president.

The It’s On Us campaign focuses on ending sexual assault on college campuses and encouraging students to create an environment on campuses where sexual assault “is unacceptable.”

Biden introduced Lady Gaga at the Academy Awards in 2016 as part of that campaign.

Biden and his wife, Jill, are launching the Biden Foundation now that Biden is out of office, and one of its focuses will be on preventing sexual assault.
