In the short time that he has been president, Donald Trump has encountered a whole host of controversies and scandals - but wall-gate has got to be the most prominent of them.
For years, the former businessman has been promising a "yuge" wall along the southern border for the purposes of keeping out so-called "bad hombres". He announced this early on in this campaign, stating: "I would build a great wall, and nobody builds walls better than me, believe me, and I build them very inexpensively."
Since then, discussions about the wall have touched on important points such as who will fund it (Mexico, of course), what it will be made of (glass, obviously, because "as crazy as that sounds, you need transparency through that wall"), and how likely it is that it'll actually be built (not very, if you ask anyone other than the president).
The trouble is, every time Trump attempts to prove how great his wall will be, someone goes ahead and demonstrates just how useless it is.
Last week, a migrant managed to jump the tall metal barrier between Ciudad Juarez in Mexico and Sunland Park, New Mexico with the help of a few friends.
The three men, who were all on the Mexican side of the border, helped the escapee by giving him a boost over the barrier, and acting as lookouts as he fled across American soil. All in all, the maneuver took less than two minutes - and nobody stopped them in the process.
"He couldn't get over! He was taking forever," said one of the men who had given the migrant a leg-up.
And this wasn't the first man that the three had witnessed scaling the wall. In fact, they said, they had seen people accomplish the feat singlehandedly in under a minute before.
This comes just days after Trump called for thousands of troops to be deployed at the border.
Last Wednesday, he signed a memo stating that the defense secretary "shall request use of National Guard personnel" to secure the border, and that "the security of the United States is imperiled by a drastic surge of illegal activity on the southern border."
"During the administrations of Presidents George W. Bush and Barack Obama, the National Guard provided support for efforts to secure our southern border," the memo says. "The crisis at our southern border once again calls for the National Guard to help secure our border and protect our homeland."
At this point, it seems that the president really can't catch a break when it comes to the border wall. Earlier on this month, for example, he was ridiculed after it transpired that pictures he'd tried to pass off as new images of the border wall under construction were actually old shots of the existing border wall.
As of yet, he has not commented on this particular incident, but the continuing influx of immigrants will no doubt spur him further in his mission to build "the best" wall - regardless of who ends up paying for it.
