"Where's My Roy Cohn?": Film Explores How Joseph McCarthy's Ex-Aide Mentored Trump & Roger Stone

Former Trump campaign adviser Roger Stone, who was arrested on Friday, and Donald Trump share a unique history: Both were heavily influenced by the infamous attorney Roy Cohn, who served as a chief counsel to Senator Joseph McCarthy during the Red Scare in the 1950s and would later become a leading mob attorney. Cohn represented Trump for years and once claimed he considered Trump to be his best friend. Cohn is the subject of a new documentary at the Sundance Film Festival titled "Where's My Roy Cohn?" We speak to the film's director, Matt Tyrnauer.
