A US Secret Service agent nearly shot Iran’s President Mahmoud Ahmadinejad in September 2006, when the Iranian leader was in New York for the United Nations General Assembly session, according to an upcoming book.

The agent was adjusting a shotgun mounted to the side of a vehicle in President George W Bush’s motorcade when the weapon was accidentally discharged, sending a bullet in the direction of President Ahmadinejad, write Marc Ambinder and DB Grady in ‘Deep State: Inside the Government Secrecy Industry,’ according to a “very short extract” published by the Atlantic magazine.

The published extract says, “The uncomfortably close call was recorded in a memo shared with a dozen high-level Bush administration officials. “One morning in September 2006, during the United Nations General Assembly, President George W. Bush’s daily intelligence brief contained a particularly chilling item.

It was three sentences long, and it scared the hell out of the dozen or so White House officials cleared to read it. According to one official, it began, ‘A US Secret Service agent, in an apparent accident, discharged his shotgun as Iranian President Mahmoud Ahmadinejad was loading his motorcade at the InterContinental Hotel yesterday.’

“At the time, the Bush administration was weighing how to deal with the Iranian nuclear-weapons program. And here a Secret Service agent had just given Iran a potentially devastating public-relations coup. Ahmadinejad was certain to reveal the accident in some grand form before the whole of the United Nations. He might allege that the United States had tried to assassinate him, and thus upend the entire conference. ‘When I read that, I remember closing my eyes,’ recalls the official.

“The agent was adjusting the side-mounted shotgun on one of the motorcade’s armored follow-up Suburbans when it discharged. ‘Everyone just stopped. The Iranians looked at us and we looked at the Iranians. The agent began to apologize. Ahmadinejad just turned his head and got into his car.’ And that was it.”

“The Iranians told no one. Their silence led several White House aides to begin to see Ahmadinejad in a new light. Here was evidence that maybe Iran was acting strategically, and therefore cautiously.”‘Deep State,’ which promises to unravel the ‘secrecy apparatus of the United States,’ will hit store shelves in April.
