AINSLEY EARHARDT (CO-HOST): They asked [Secretary of Homeland Security Kirstjen Nielsen], are children put in cages? What's your response to that -- that were built during the Obama administration? 

MARK MORGAN (FORMER BORDER PATROL CHIEF): Right, and that's a great -- it's totally a false narrative, it's a talking point for the Democrats. They're not cages. They're actually really nice facilities. And there are chain link fence within the facilities, but it's designed so the Border Patrol agents working there can provide safety and security for the people that are there. And, remember, they're only there for max 72 hours before they've got to be released.
