CBP chief says Mexican state stopped taking back some migrant families days after Biden inauguration

The acting head of Customs and Border Protection (CBP) said this week that a Mexican state through which many migrants travel into the U.S. stopped taking families with small children just days into the Biden administration -- a move that contributed to the administration releasing families into the U.S.

While it has been expelling single adults and migrant families via Trump-era Title 42 public health protections, it has repeatedly said it has not been able to expel some families with children under the age of 7 due to the refusal of Mexican officials to take them. Acting CBP Commissioner Troy Miller told House lawmakers on Wednesday how a surge that would go on to overwhelm authorities in the Rio Grande Valley sector began just days after President Biden was inaugurated on Jan. 20 – when Tamaulipas, a northern Mexican state, stopped accepting families with young children.
