Southwest Key has long managed shelters for migrant children. A spotlight was cast on the low-profile nonprofit four years ago when a surge of adults and lone children traveled up to the border from Central America. Now it’s getting a reported $458 million to shelter more children.

Mark Greenberg worked for a division of Health and Human Services that managed shelters for those unaccompanied children in 2014 and now works with the Migration Policy Institute, a nonprofit think tank in Washington, D.C.

"It’s a new crisis but this one is happening not because of unforeseen events outside but rather because of the policy decision to implement family separation," he said.

President Donald Trump ended the policy Wednesday afternoon amid a backlash, but it’s not clear what will happen with the more than 2,300 children already in shelters.

"It’s just not obvious that there was a lot of planning or thinking through how to address these very basic issues," Greenberg said.

As for new incarcerations, the president’s order says new facilities will be found to house families together. It reads specifically that the country’s Department of Defense will need to find places to house them.
