President Trump said he wants his proposed border wall with Mexico to be see-through so that border agents don't get hit with "large sacks of drugs" being thrown over the wall.

"You have to be able to see through it," Trump said of the wall he's promised to build. "In other words, if you can't see through that 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.

"And I'll give you 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 on the head with 60 pounds of stuff? It's over. As crazy as that sounds, you need transparency through that wall. But we have some incredible designs."

He also insisted to media on Air Force One that he isn't kidding about putting solar panels on the wall.

"There is a chance that we can do a solar wall," Trump said in the newly released remarks from Wednesday. "We have major companies looking at that. Look, there's no better place for solar than the Mexico border — the southern border — and there is a very good chance we can do a solar wall, which would actually look good."
