I was looking for this chart when I composed my previous message. I wanted to use it to illustrate that Trump's claims of a crisis on the border are untrue. Border apprehensions over the past decade have been far lower than all years prior until you get back to the early 1970's, i.e., lower than at any time over the past half century. Trump manufactured the crisis out of thin air.
Trump deals only in extremes. For him everything is either the best or the worst. Almost invariably he's making it up.
We're only running short of holding facilities because Trump is trying to end the "apprehend and release" approach. Independent of whether that's the right thing do, ending it means there will need to be greatly increased holding capacity, which Trump is loath to do.
Funny, I've heard a lot of interviews with ICE and border patrol people over the last year or so and they are very clear that there has been a crisis for some time that they are not equipped to handle for lack of funding, thanks of course to the Democrat Congress. They say a wall would help a lot.
