Not to house them.
Any funds expended should have only one purpose - repatriation to the country of origin. And a general warning to all who would attempt to “return” to US soil - serious detention time under rigorous conditions, in an unpleasant environment.
There is a very easy way to avoid such detention - don’t attempt to jump the line again. There is an existing path for legal access to US soil, and it is expected that every visitor will abide with that path.
Save our funds for a REAL emergency when it comes up. Like when the MS-13 infiltrators band together again within the US borders and start their predations on the local community. Or the Islamic jihadists who are using the same cover to slip in.
I was telling you what Obama has requested the funds for.
That is the way it should be.
