Situational update - the Mexicans *have* been trying to turn them back at their southern border and deporting them when found in their interior. Even though Biden is welcoming illegals, it would actually be worse if the Mexicans weren’t doing what they can. FYI, the Mexican government no longer has the ability to do more than they already are - you have to realize the cartels mostly won.
Oh?
They can't even control THEIR southern border?
Them Hondurans and Guatamala folks ain't walking for weeks thru Mexico with no help from Mexico!
