It’s a running joke in the White House that one of the worst jobs in the administration belongs to the poor souls charged with designing the president’s border wall. Trump, of course, talks about the wall all the time with a gleam in his eye. Running for president, he vowed that he would build “a great wall, and nobody builds walls better than me, believe me, and I’ll build them very inexpensively…And I will have Mexico pay for that wall. Mark my words.” He admonished rival candidate Jeb Bush for talking about border fencing: “It’s not a fence, Jeb. It’s a WALL, and there’s a BIG difference.”
