Sean Hannity tonight took on Rep. Luis Gutierrez (D-Ill.) over the southern border.

A senior Homeland Security official confirmed that ISIS may be attempting to enter America through the southern border. Still, Gutierrez said that 2,000 jihadists with ISIS aren’t going to cross the border – they’re going to enter with visas.

Gutierrez also said that the border can’t be secured without immigration reform.

“If you can pass a bill to secure the border first, would you support that?” Hannity asked.

"No! Because it would be folly. It would be folly and I would be derelict in my duty to protect America,” he said.

“If you don’t do it, it’s a dereliction of duty,” Hannity fired back. “Secure the border!”
