Ashley Greene, one of the fresh-faced (or perhaps pale-faced) vampires from the "Twilight" movie series, made her Capitol Hill debut Wednesday. She spoke to reporters and staffers about a new study on domestic violence and sexual assault, as part of the roll-out of the new "No More" movement. "Simply telling a friend that you support them and they don't deserve to suffer can make an enormous difference," she implored. Afterward, she took to Twitter with a sigh of relief. "I was very nervous," she wrote. "Hopefully I did OK. Either way I'm proud to have been a part of this movement."
