“What we know as lawyers, is that in a short amount of time, we are going to be in court and we’re going to be witnessing, I presume, people carrying babies into the court sitting them down, I don’t know, alone on someone’s lap, in front of a judge, across from a well-trained, highly paid, government ICE prosecutor, and that child is going to have to face a complex deportation hearing alone,” Ryan explained. “In addition to being detained away from their parents, the legal services that the government provided by a matter of law are slowly being stripped away.”

Like the administration’s new “zero tolerance” policy, ending funding for attorneys to represent the detained children is also a new policy.

“Just 30 days ago, my organization — which provides direct representation through government funding to children, these babies — got an e-mail saying ‘stop working immediately,'” he revealed. “We can no longer provide direct representation to these children.”

“Why?” Ruhle followed-up.

“The government made a decision to issue a stop work order,” he replied.

“No one is defending the children?” she asked.

“These children have no access to independent counsel,” he answered.
