Lady Gaga made a powerful statement about sexual assault at the Oscars, belting out her nominated tune from “The Hunting Ground,” a documentary about rape on college campuses.<br />Vice President Joe Biden introduced the songstress, charging the crowd, “Tonight, I’m asking you to join millions of Americans … to take the pledge.<br />A pledge that says, ‘I will intervene in a situation where consent has not or cannot be given.'”<br />Wearing a white suit and sitting behind a white grand piano, Gaga sang the first several verses of “Til It Happens To You” before being joined by dozens of sexual assault survivors on stage.<br />The young men and women standing alongside Gaga had blunt messages scrawled on their arms, such as “Not Your Fault” and “It Happened To Me.”<br />Gaga herself is a survivor of rape, which happened at the age of 19.
