Inspired by a viewing of James Vanderbilt’s 2015 film “Truth,” Visiting Senior Lecturer in English Todd Brewster’s Introduction to Journalism class welcomed a surprise guest: American journalist and producer Mary Mapes. The film, set in 2004, follows Mapes, producer of CBS News program “60 minutes,” and its anchor, Dan Rather, as they cover one of their biggest stories: an investigation of then-President George W. Bush’s history of military service and how he avoided being drafted into Vietnam using his father’s connections.
