Guest column by Allie Cohen | How social media shaped my 9/11 story

A hidden gem of Penn, the course provided a stipend to fly to any Presidential Library to do research for the course’s assignment of a 30-page paper. I flew to Dallas, Texas, where I studied George W. Bush’s epideictic rhetoric in his three major post-9/11 speeches.
