INTERESTING TAKE ON 'THE WALL' AT MOTHER JONES: yeah it has been funded four times, but never 'built.' First time under The Rapist. Article from 2016 points out what POTUS will have to do (and hence much he has done kek) and what had already been done. Also mentions a coupla contractors worth diggin on imo. And it still begs the question, what happened to all the prior funding for 'walls' that never got built?

Although wall construction began during Bill Clinton’s administration, the Department of Homeland Security (DHS) built most of the approximately 700 miles of fencing after the Secure Fence Act of 2006 was passed. Sen. Hillary Clinton voted in favor of that Republican-introduced bill, as did 26 other Democrats. “I voted numerous times when I was a senator to spend money to build a barrier to try to prevent illegal immigrants from coming in,” she commented at one 2015 campaign event, “and I do think you have to control your borders.”

The wall-building project was expected to be so environmentally destructive that then Homeland Security chief Michael Chertoff waived 37 environmental and cultural laws in the name of national security. In this way, he allowed Border Patrol bulldozers to desecrate protected wilderness and sacred land. “Imagine a bulldozer parking in your family graveyard, turning up bones,” Chairman Ned Norris, Jr. of the Tohono O’odham Nation (a tribe whose original land was cut in half by the border) told Congress in 2008. “This is our reality.”

With a price tag of, on average, $4 million a mile, these walls, barriers, and fences have proved to be one of the costliest border infrastructure projects undertaken by the United States. For private border contractors, on the other hand, it’s the gift that just keeps on giving. In 2011, for example, the DHS granted Kellogg, Brown, and Root, a subsidiary of Halliburton (one of our “warrior corporations“), a $24 million upkeep contract.
