Who could not have predicted this heartbreaking turn of events? Via NBC News:

WASHINGTON — Lawyers appointed by a federal judge to identify migrant families who were separated by the Trump administration say that they have yet to track down the parents of 545 children and that about two-thirds of those parents were deported to Central America without their children, according to a filing Tuesday from the American Civil Liberties Union.

The Trump administration instituted a "zero tolerance" policy in 2018 that separated migrant children and parents at the southern U.S. border. The administration later confirmed that it had actually begun separating families in 2017 along some parts of the border under a pilot program. The ACLU and other pro-bono law firms were tasked with finding the members of families separated during the pilot program.

Unlike the 2,800 families separated under zero tolerance in 2018, most of whom remained in custody when the policy was ended by executive order, many of the more than 1,000 parents separated from their children under the pilot program had already been deported before a federal judge in California ordered that they be found.
