On Friday, officials from the Trump administration said it would require too much effort to reunite the thousands of families it separated before implementing its “zero-tolerance” policy in April, according to a declaration filed as part of an ongoing lawsuit between the American Civil Liberties Union and U.S. Immigration and Customs Enforcement. Last month, the inspector general of the Department of Health and Human Services released a report stating that “thousands” more immigrant families had been separated than the government had previously disclosed. In the declaration submitted Friday, HHS officials said they don’t know the exact number of children who were taken from their parents before “zero tolerance” and that finding them would be too much of a “burden” since there was no formal tracking system in place. “The Trump administration’s response is a shocking concession that it can’t easily find thousands of children it ripped from parents and doesn’t even think it’s worth the time to locate each of them,” said Lee Gelernt, the lead lawyer in the ACLU’s ongoing lawsuit against ICE, in a statement. “The administration also doesn’t dispute that separations are ongoing in significant numbers.” HHS did not respond to HuffPost’s request for comment. The deputy director of the Office of Refugee Resettlement, Jallyn Sualog, said that 100 ORR analysts would have to work eight hours each day for between seven and 15 months to “even begin reconciling” data on separated families. “In my judgment, ORR does not have the requisite staff for such a project,” Sualog wrote in the declaration. Immigration advocates are appalled by the fact that the government didn’t bother to properly track separated families and that it is now shirking its responsibility to reunite parents and children.

They are saying they just don’t care. It’s shocking from a human rights perspective for a government to behave this way. Michelle Brané, the director of the Migrant Rights and Justice Program at the Women’s Refugee Commission
