Republican politicians were hoaxed over the weekend by an image purporting to be a downed US warplane crew member rescued by military special forces in Iran on Saturday, igniting a call for a national “crash course in media literacy”.

Greg Abbott, the Texas governor, Ken Paxton, the state’s attorney general and a US senate candidate and Mike Lawler, a New York representative, were all caught out for “liking” a fake picture of the airman, who has not been publicly identified.

Donald Trump on Monday afternoon was scheduled to hold a news conference in which he was expected to discuss details of the rescue mission.

The AI-generated image that fooled the Republican politicos was shared by a pro-Trump X account. The supposed airman is shown surrounded by smiling military members, with a US flag draped across his lap.

After Abbott’s error, Billy Binion of the libertarian magazine Reason wrote: “This kind of stuff is bleak. I get that we’re in a new era, but we desperately need a new crash course in media literacy, or just a reminder to be remotely discerning.”
