The Kino Border Initiative reports:
Since MPP returns to Nogales began on January 2nd, CBP has already returned particularly vulnerable individuals, including 3 two-year-old children, 2 one-year-old babies and 3 families that are primarily Mam speaking (despite the fact that indigenous language speakers, especially of non-Mexican languages, shouldn’t be subject to MPP).
In the last week, at least two families were separated as a result of MPP, including a man who was returned while his pregnant wife was released in the US, and a woman with children returned whose husband remains detained.
