After deaths of children, Democrats push bill on how border agency should treat migrants

Leah Chavla, an international human rights lawyer and policy adviser at the Women's Refugee Commission, has previously said that CBP already has a set of guidelines in place that outline the conditions and resources the agency has to provide to children and other migrants in its custody.

But unlike laws, guidelines are not binding.

“It's important to have a critical look at what's going on and how the guidelines can be made binding,” Chavla said.
