Following what one attorney described as months of deliberate stonewalling, the Trump administration has finally handed over key data that could help legal advocates reunite immigrant families separated under the Justice Department\u0026#039;s destructive \u0022zero tolerance\u0022 policy.In a court filing (pdf) Wednesday, attorneys with the ACLU said they have not yet been able to locate the parents of 628 children, down from 666 last month. The filing revealed that the Trump administration provided \u0022information from another government database that had not previously been disclosed (the Executive Office for Immigration Review)\u0022 last Wednesday, the day before Thanksgiving.\u0022Not only has the Trump administration not been helping us, but it\u0026#039;s now clear they failed to disclose information in their possession.\u0022 —Lee Gelernt, ACLU\u0022Among other things, the information includes phone numbers that had not previously been disclosed,\u0022 the court document reads.Lee Gelernt, deputy director of the ACLU Immigrants\u0026#039; Rights Project and one of the lawyers working to reunite families, told CNN that \u0022we\u0026#039;ve been asking them for any additional information they have forever and we only finally got this information after outcry that parents still could not be found and the issue reached the presidential debate level.\u0022\u0022We hope we can find a significant number of parents and children through this information,\u0022 Gelernt added. \u0022But make no mistake about it: Not only has the Trump administration not been helping us, but it\u0026#039;s now clear they failed to disclose information in their possession.\u0022During the pre-election presidential debate in October, President Donald Trump claimed his administration was \u0022trying very hard\u0022 to reunite the families it separated—contradicting the accounts of lawyers and advocates—but expressed no regret over ripping children from their parents, a practice psychiatrists and human rights organizations have denounced as torture.\u0022Children are brought here by coyotes and lots of bad people, cartels,\u0022 Trump said, a claim immigrant rights groups refuted.In response to the new court filing, government watchdogs and lawmakers demanded a probe into the Trump administration\u0026#039;s intentional withholding of information that could prove critical to reuniting hundreds of families.Unconscionable. Who made the call to not release this information sooner? We have to demand accountability now or this can and will happen again. https://t.co/RiQNm8fnBi— Liz Hempowicz (@lizhempowicz) December 3, 2020Rep. Joaquin Castro (D-Texas) tweeted late Wednesday that \u0022a human rights commission should investigate what happened, even refer prosecutions.\u0022\u0022These families belong together here in the United States,\u0022 said Castro.
