To be fair, most/all those weren’t from Mexico but from countries south of Mexico, trekking across Mexico on the way to the USA.
Still, the question that has yet to be asked, is why Mexico is allowing other countries to cross their southern border when they've been long known to strongly guard that border? Why is this occurring now?
I wonder why the Mexican government doesn’t stop those
illegals into their country from south of them. They sure
stop “illegal” American entries into Mexico. HUH HUH??
