I know its very ironic. And there is even a bill being proposed to make that DC wall a permanent one. Though, I think with all the advance contracts its going to make it hard to take down the border wall. Sure he might be able to stop new wall from being funded/authorized starting today.

There are things already in motion. Authorized, funded and in progress, so it'll be interesting to see if he can manage to stop it. I don't think he'll be able to do that but after these 5 past years I've learned to never say something will/wont happen with certainty.

And I imagine in the way it was built, it is probably listed as some kind of national monument or critical infrastructure or something that would need an act of congress to remove it.
