In immigration news, attorneys with the American Civil Liberties Union working to identify families that were separated at the U.S.-Mexico border say they haven’t been able to find the parents of 545 children in U.S. custody, as most of those parents have already been deported to Central America. NBC News reports the ACLU and other legal groups were appointed to help reunite children taken from their parents under a Trump administration 2017 “zero tolerance” pilot program which separated over 1,000 families. Only about half of them have been reunited. The government also does not know the whereabouts of a number of the children.
