SAN ANTONIO, TEXAS — Homeland Security Deputy Secretary Elaine Duke told a roomful of Border Patrol agents and national law enforcement officers Wednesday that the department will no longer “segregate” interior immigration enforcement and border security.

“We used to distinguish between border security and interior enforcement. Now we’re lumping it all under border security,” Duke told hundreds of Customs and Border Protection, Border Patrol, and related sub-DHS agencies at the Border Security Expo. “We don’t believe we can segregate and say we’re going to look at the physical border, even at the border, ports of entry, between ports of entry, and then the interior piece. That’s all part of the system.”
