The Trump administration wants up to two years to find potentially thousands of children who were separated from their parents at the border before a judge halted the practice last year. The Justice Department said in a court filing late Friday, April 5, 2019 in San Diego that it will take at least a year to review the cases of 47,000 unaccompanied children taken in custody between July 1, 2017 and June 25, 2018.
