Tonight s Oscars were filled with award winners and speeches. However, there was no moment that had a larger collective impact on those watching than Lady Gaga s performance, which brought a standing ovation and tears to the eyes of many in the audience.That s because she performed her Oscar nominated song Till it happens to you, from the documentary The Hunting Ground, which explores rape on college campuses in the U.S. Here s the video:Lady Gaga was introduced by Vice President Joe Biden, who spoke about the White House s  It s On Us  campaign, urging everyone to get on board. After receiving a standing ovation, Biden said: Lets  change the culture so that no abused woman woman or man ever feels they have to ask themselves,  What do I do?  They did nothing wrong.
