I know how to stop the caravan.
Send a bunch of military nurses down there, with truckloads of EVERY VACCINE WE HAVE.
Every man, woman and child HAS to have ALL of them before they are allowed across the U.S. border.
Then, while they're all still zombified after getting shot full of toxins, force them to complete reams and reams of forms.
The paperwork will make the grad school admission tests and applying for a mortgage look like a cakewalk.
No exceptions.
Then we'll see who really wants to be here.
