President Trump leaves the NATO summit in Turkey on an older Air Force One aircraft after U.S. officials cite a credible threat from Iran and its proxy groups, according to The New York Times and CBS News. Both outlets report that the Secret Service advises a change in plans to increase safety, urging Trump to depart Turkey using the older plane rather than the Qatari-donated jet that had been used or prepared for travel. The reports say the shift raises questions about the security and suitability of the Qatari-donated aircraft in the context of the threat assessment. Details of the specific threat are not fully described in the accounts, but both outlets link the decision to the same underlying risk concern and describe it as “credible.” The Secret Service’s recommendation and the subsequent departure are presented as a response to intelligence information indicating potential targeting by Iran and allied proxy actors during the timeframe of the summit. The reports do not indicate any confirmed attack during the departure process.
