This appears to actually have Mexico taking responsibility for the medical costs of people fleeing their dysfunctional country. I would think that would be a good thing, not something that people here would complain about. Mexico has been very reluctant to take any responsibility of any kind for them, and if this is true, it’s a significant step in the right direction.
Why would you think that? Why do they need us to agree to help? They don't take care of their people now, with millions of aid from us every year, they're not going to start.
