Border conditions are 'because Congress has let it happen': Acting USCIS director

Acting U.S. Citizenship and Immigration Services Director Ken Cuccinelli said that conditions at border detention facilities are "because Congress has let it happen."

"When Congress provides the professionals at the border what they need, success happens. Success being measured as avoiding overcrowding," he told ABC News Chief White House correspondent Jonathan Karl on "This Week" Sunday.

Cuccinelli went on to call for Congress to close "asylum loopholes" to discourage illegal immigration.
