SAN DIEGO (KGTV) -- The ACLU said Tuesday night that 400 parents may have been deported without their children.
US District Judge Dana Sabraw set the Thursday reunification deadline last month after the ACLU filed a lawsuit over the family separations.
A little more than 1,000 parents have been reunified with their children as of Tuesday night, the ACLU continued.

"This is a remarkable achievement," Sabraw said, noting that the reunification of eligible children between age 5 and age 17 should be mostly completed by the time of the next court hearing on Friday afternoon.
A government attorney told Sabraw that 914 parents are ineligible to be reunited with their children for various reasons, including prior criminal pasts.
The judge ordered the Department of Justice to provide a list of parents who waived reunification prior to being deported by noon Wednesday.

Government attorneys claimed in previous proceedings that parents being deported had the right to take their children with them, but decided not to, hoping their children would be allowed to stay in the United States.
Last week, Sabraw issued an order temporarily blocking the federal government from deporting parents who were separated from their children at the border.
