Hundreds of migrant children who were forced into separation by the Trump administration’s “zero-tolerance” immigration policy were not reunited by a court-ordered deadline on Thursday, July 26.

According to a court filing explained by CNN, the deadline was supposed to require the Trump administration to reunite more than 2,000 children ages five and older. But by the Thursday deadline, they had reunited just 1,442 families.

Now there are more than 700 children who won’t be reunited with their families any time soon — some of their families have already been deported, and others the government claimed denied to be reunified or had criminal histories, according to CNN.

The American Civil Liberties Union (ACLU), which is fighting to reunite these families and force the government’s hand to meet these deadlines, said in a press release that it will continue fighting until the families are all reunited.

“These parents and children have lost valuable time together that can never be replaced. We’re thrilled for the families who are finally reunited, but many more remain separated,” Lee Gelernt, deputy director of the ACLU’s Immigrants’ Rights Project, said. “The Trump administration is trying to sweep them under the rug by unilaterally picking and choosing who is eligible for reunification. We will continue to hold the government accountable and get these families back together.”

The ACLU and the U.S. government disagree over the eligibility requirements to be reunified — and the government decided on Thursday that all the remaining 711 families were ineligible, according to CNN. Over 100 children’s parents declined to be reunified, according to the news outlet, but immigration advocates aren’t so sure these parents knowingly waived their rights to take their children with them.

“Our attorney volunteers working with detained separated parents are seeing lots of people who signed forms that they didn’t understand,” Taylor Levy, a legal coordinator at Annunciation House in El Paso, Texas, which assists immigrants, told The New York Times. “They thought the only way they would see their child again is by agreeing to deportation.”

Another 21 children couldn’t be reunited with their families because their parents had red flags in their background checks, and 46 children’s parents had red flags for other reasons. The parents for 79 children had been released from custody into the U.S. but could not be reunited, 431 children’s parents were likely deported, 94 children’s parents whereabouts were under review, and seven children were impacted by a different court case, all according to CNN. The numbers don’t add up to 711 due to some overlap, CNN reported.

“Some of this information is unpleasant,” U.S. District Court Judge Dana Sabraw, who ruled on the deadline, told CNN on Thursday. “It's the reality of the case, it's the reality of a policy that was in place that resulted in large numbers of families being separated without forethought as to reunification and keeping track of people. And that's the fallout we're seeing. There may be 463, there may be more, it's not certain, but it appears there's a large number of parents who are unaccounted for or who may have been removed without their child.”
