AUSTIN, Texas -- The President's family separation policy reversal is creating a lot of confusion. Government officials are trying to get clear guidance on its implementation.

Immigration law expert Denise Gilman spoke with Capital Tonight’s Karina Kling about how the 2300 children already separated from their parents will be reunited.

“Unfortunately, nobody seems to know -- even the government agencies that should be charged with reuniting these families,” Gilman, who directs the Immigration Clinic at the University of Texas Law School, said. “Advocates have been trying to get more information to understand what proceedings are going to be but there’s little information to be had.”

Gilman said the reunification process is not easy.

“We know from experience that in many of these cases the parents and children do not even know where the other one is, much less have a process for reuniting them. So it's a deep concern,” Gilman said.
