Vice President Joe Biden introduced Lady Gaga’s original song-nominated performance at the Oscars with an exhortation that people step up and put an end to sexual assault.
Calling himself ‘‘the least qualified man here,’’ Biden encouraged the audience to help change the culture by intervening in situations where consent has not or cannot be given.
The vice president then introduced Lady Gaga, who sang and played piano on"Til It Happens to You,’’ a song she co-wrote for ‘‘The Hunting Ground.’’
Gaga was joined by several victims of sexual assault, who had messages written in black on their bare arms.
The rape survivors featured in Lady Gaga’s performance received a star-studded send-off as they filed out of the Dolby Theatre through the audience.
A jubilant Brie Larson embraced almost every woman and man as they walked past her front-row seat.
Kate Winslet stood up to hug members of the group.
Diane Warren, who co-wrote ‘‘'Til It Happens to You’’ with Gaga, immediately positioned herself at the bottom of the stage’s steps to offer hugs and kisses following the moving performance.
