In June 2009, Jones was sent to Tehran just prior to the controversial 2009 presidential election. Jones' reports in Iran included an interview with "Newsweek" journalist Maziar Bahari, who was arrested after the disputed June 2009 presidential elections. During Bahari's time in prison, his interrogators charged him with espionage and used Jones' interview as evidence against him. It was later clarified by Bahari that the charges were fabricated. Jones appeared as himself in the film version of Bahari's ordeal, "Rosewater", encountering Bahari prior to taping their interview. The film was written and directed by "Daily Show" host Jon Stewart. Another segment in Iran poked fun at Iranians' greater knowledge of the United States compared with Americans' knowledge of Iran. That segment, along with a 2011 piece in which he invited cameras to his vasectomy, are regarded by "TV Guide" as his signature segments on the program.
