Ahmadinejad's policies and thinking but he was not involved in the hostage drama nor in the assassination of an Iranian opposition Kurdish leader in Vienna." A classified CIA report says the claim is not proven. With Ahmadinejad's recent publicity, five former U.S. hostages Dr. William Daugherty (who worked for the CIA in Iran), Kevin Hermening, David Roeder, US Army Col. Charles Scott, and US Navy Capt. Donald Sharer have alleged that Ahmadinejad was one of the leaders of the Iran Hostage Crisis at the U.S. embassy in Tehran, during their 444-day captivity starting on November 4, 1979. All of the above-mentioned hostages have claimed that Ahmadinejad is the man whom they remember from their captivity. Ahmadinejad denies his presence in the embassy, other hostages are unsure about the identification and the CIA has reportedly questioned this identification. Col. Charles Scott, now seventy-three, recently told the Washington Times that "He was one of the top two or three leaders; the new president of Iran is a terrorist." Col. Scott claimed to recall an incident when Ahmadinejad berated a friendly Iranian guard who had allowed the two Americans to visit another U.S. hostage in a neighboring cell. Col. Scott, who understands Persian, said Ahmadinejad told the guard: "You shouldn't let these pigs out of their cells". Donald Sharer, a retired Navy captain who was for a time a cellmate of Col. Scott at the Evin prison in northern Tehran, remembered Ahmadinejad as "a hard-liner, a cruel individual". "I know he was an interrogator", said Capt. Sharer, now 64. Former hostages William Daugherty and Kevin Hermening also claim he was involved. Scott and Roeder have also expressed certainty that Ahmadinejad was present at their interrogations. Scott asserted his certainty forcefully, stating: "This is the guy. There's no question about it. You could make him a blond and shave his whiskers, put him in a zoot suit and I'd still spot him." Both men, along with Sharer and Hermening, have stated their recollections of Ahmadinejad as an "extremely cruel" ringleader. Of the above men, only Hermening has expressed that he was not immediately sure that Ahmadinejad was involved in the Hostage Crisis. However, former hostages USAF Col. Thomas E. Schaefer, Paul Lewis (a former Marine embassy guard), and Barry Rosen (former embassy press attache) have expressed uncertainty regarding whether Ahmadinejad was actually involved. Schaefer stated that he does not recall Ahmadinejad by face or
