There are 2,047 children that must be placed in the same facility as their parents within the next two to four weeks. But U.S. law and a series of court rulings that limit the amount of time minors can be held in detention will further complicate those reunions.

A June 18 CBS News poll showed 67 percent of Americans found separating undocumented immigrant children and parents at the border "unacceptable."

"(The) family separation crisis is not over. We have a situation where the Trump administration seems to be aiming to detain families," said Karthik Ganapathy, a MoveOn.org spokesman.
