Actress and comedian Amy Schumer and her cousin, Sen. Chuck Schumer, joined forces for the second time in New York City to urge residents to take action through social media and traditional advocacy to help tighten gun laws. The senator and his famous cousin appeared outside City Hall in Manhattan on Sunday to promote their “crusade against guns. The relatives first held a press conference in New York after gun violence at a movie theater in Lafayette, Lousiana earlier in the summer at the showing of “Trainwreck,” a movie in which Amy Schumer starred. The shooting killed two women and injured at least nine others.
