On Wednesday night, President Trump informed reporters on Air Force One that his proposed border wall needs to be see-through, or at least have holes in it, so Americans don't get crushed by falling bags of drugs, the White House transcript of the conversation shows. Trump reportedly held court with the traveling press pool for more than an hour while en route to Paris for a meeting with French President Emmanuel Macron.

"One of the things with the wall is, you need transparency," Trump said. "You have to be able to see through it. In other words, if you can't see through the wall — so it could be a steel wall with openings, but you have to have openings because you have to see what's on the other side of the wall."

Trump then offered reporters "an example."

"As horrible as it sounds, when they throw the large sacks of drugs over, and if you have people on the other side of the wall, you don't see them — they hit you in the head with 60 pounds of stuff? It's over," Trump said. "As crazy as that sounds, you need transparency through that wall."

As crazy as it sounds, indeed. Jeva Lange
