Immediately after the election, the Mexican congress secretively passed a new and unusual law that had been pre-written and a pathway for its quick approval cleared.
The law would be implemented 60 days later, on January 11, just before Trump was to leave office. Boiled down, the law prohibited federal detentions of migrant families with minor children — with or without parents — in all 58 Mexican detention facilities nationwide.
This meant that after January 11, 2021, Mexico could start emptying its detention centers, and thousands of families with their young children could travel freely inside the country, which everyone knew meant the U.S. border.
But
what to do about Title 42, the COVID pandemic rule Trump had used to keep out those who tried to cross? The law addressed that: It gave individual Mexican states authority to
refuse U.S. Title 42 expulsions — if the states deemed the private shelters as too full or to be closed for COVID.
