Acting Director of Immigration and Customs Enforcement Thomas Homan castigated sanctuary cities as “un-American” in a new interview.

“Sanctuary cities, in my opinion, are un-American,” Homan said during an interview with the Washington Examiner published Monday.

Homan said jurisdictions that adopt sanctuary city policies are increasing crime in and around them.

“In the last year, I’ve read all these stories of how the crime rate has exploded in Chicago, and the president’s trying to help them,” Homan said. “We’re stepping up our game in Chicago. Is Chicago doing everything that it can to decrease the criminal activity up there? I say no.”
