In this Jan. 25, 2019, file photo, a migrant who did not give his name looks on with his children as they wait to hear if their number is called to apply for asylum in the United States, at the border in Tijuana, Mexico. Associated Press/Gregory Bull ACLU lawyers said in a legal filing that they haven't been able to find the parents of 545 migrant children separated by the Trump administration at the US-Mexico border, NBC News reported Tuesday. The lawyers said they believe the administration has already deported around two-thirds of the parents to Central America without their children, according to NBC News. Trump ended his notorious family separation policy in June 2018 following public outcry, and a court ordered his administration to reunite thousands of families.
