A rock climber has shown just how easy it is to climb US President Donald Trump's wall.
Rick Weber from Kentucky built a replica of the fence the US is building on the border with Mexico, which Trump said would be "virtually impenetrable".
"You never tell a rock climber something is impossible to climb or someone is going to be trying it," Weber told CBS News.
The replica is based on official designs of the wall, standing 5.5m tall with a plate at the top. It didn't take long for Weber to figure out how to conquer it.
"Throw a weight over with a thin line, pull up a rope. They made it nice that it's open down here at the bottom so you can pull your rope through and tie it at the bottom, and then just ascend the rope and descend the other side."

And you don't need to be an experienced rock climber to do it. An eight-year-old girl was able to make it over without much difficulty, video uploaded by her mother proved.
And an experienced climber was able to do it in barely more than 30 seconds.
Weber has invited others to try it for themselves at an upcoming climbing event, 'Rocktoberfest'.
"Speed contests are pretty popular now and we have a category and a trophy awarded for the cleverest, the cleverest technique for getting up and over the wall."
Weber says he's excited to see all the different methods climbers will use to get over the wall.
"I'm not making an argument that we shouldn't have a secure border," he told Time magazine. "I'm not doing that at all. What I'm trying to do is to make sure that we're not blowing a lot of money on some silly nonsense of putting up something that he thinks can't be climbed. Because it can. And will be."
Trump has repeatedly made false claims illegal immigration from Mexico is at record levels.
