Several major news outlets have claimed that US President Donald Trump effectively used journalists covering his travels as decoys last month when he secretly switched planes due to a suspected Iranian assassination plot.

Initial media reports said Trump abruptly switched from his Qatari-gifted Boeing 747-8 to an older Air Force One while returning to the UK from a NATO summit in Türkiye after receiving intelligence about a potential plot to assassinate him. The switch was reportedly made because the older aircraft has more advanced life-support and security systems.

On Monday, several outlets reported new details, alleging that Trump had boarded the older Air Force One before being secretly transferred in an airport catering truck to a smaller military aircraft, which flew him to the UK. Once there, he reportedly re-boarded the older Air Force One, creating the impression that he had traveled aboard it the entire time.

News organizations including Reuters, CNN, the Washington Post, and the New York Times argued that the move potentially put the lives of journalists and administration staffers traveling aboard the presidential plane at risk. According to CNN senior reporter Aaron Blake, journalists felt they had been treated like “unwitting and unknowing decoys very much in the line of fire.”

President Bill Clinton used a decoy plane while traveling to Pakistan in 2000, but reporters traveling with him were briefed about the arrangement off the record beforehand.

Trump, who has often accused journalists of spreading lies about him, said on Tuesday that he had acted on the advice of the Secret Service and the military. White House spokeswoman Karoline Leavitt said last month that although the new Air Force One was “perfectly safe for the president’s travels,” it was slated for additional enhancements.

The Department of Justice attempted to subpoena New York Times journalists over their reporting on the new Air Force One, while the Pentagon recently revoked the security clearance of former Air Force chief Frank Kendall, whom it accused of leaking classified information about the aircraft to the media.

The US and Israel killed dozens of Iranian political and military leaders in targeted strikes, including the country’s longtime supreme leader, Ali Khamenei. Iranian officials vowed to avenge their deaths, while protesters in Tehran and other cities called for Trump to be killed.
