Surprise, surprise —Trump lied — again. Rock climbers will demonstrate how easy it is to climb his border wall.

So, Trump lied again :

A rock climber plans to hold a border wall climbing competition after President Trump recently declared a new section of his border wall with Mexico “impossible to climb,” according to a new report from climbing magazine Rock and Ice.

Rick Weber — a 75-year-old retired engineer, and active rock climber certified by American Mountain Guide Association as a Single Pitch Instructor — writes that he has built a replica of an 18-foot tall section of steel border wall and has invited rock climbers to compete in the climb on Oct. 11 and 12. “We will be hosting the event on land my wife and I own in the Red River Gorge region of eastern Kentucky,” Weber wrote in Rock and Ice. “[It] coincides with one of the largest gatherings of climbers in the U.S.—an annual event called Rocktoberfest.”

Trump announced that 20 of the most skilled mountain climbers out there had been tasked with trying to scale the wall, but were unable to do so. “We have, I guess you could say, world-class mountain climbers. We got climbers,” Trump said … “We had 20 mountain climbers. That’s all they do — they love to climb mountains. They’re very good, and some of them were champions. And we gave them different prototypes of walls, and this was the one that was hardest to climb.”

Those in the climbing community, however, have raised questions over Trump’s claims of a climbing test. Weber wrote in the post announcing his competition that “no one in our climbing community knows any of these 20 mountaineers.” Some professionals said that the claim was “preposterous.” Jesse Grupper, a gold medalist in this year’s USA Climbing Sport & Speed Open National Championships, said he “never heard of any climbers ever being recruited to try and climb a border wall.”
