Louisiana Gov. Bobby Jindal (R) on Wednesday stood behind his declaration that European cities have Muslim “no-go zones” and went on to say that if the U.S. wasn’t careful, it would be seeing its own “no-go zones” soon.

The term, a reference to alleged areas under Muslim control that follow Sharia law and are off-limits to the police, came under widespread criticism last week after a self-styled terrorism expert on Fox News said all of Birmingham, England was a “no-go zone.”

Fox News was later forced to apologize multiple times for its coverage of Muslims in Europe and admitted there is no credible evidence such areas exist.

Despite that, Jindal used the phrase this weekend during a speech in London and has repeatedly said that the “zones” exist.

On Wednesday, Fox host Neil Cavuto provided the governor an opportunity to walk back the terminology. But Jindal would not relent.

“If people don’t want to come here to integrate and assimilate, what they’re really trying to do is set up their own culture, their own communities,” Jindal said. “What they’re really trying to do is overturn our culture. We need to recognize that threat.”

“If we don’t, we’re gonna see a replica of what’s happening in Europe in America,” Jindal continued. “We’re gonna see our own no-go zones if we’re not serious about insisting on assimilation and integration.”

Cavuto also asked Jindal to comment on former MSNBC guest Arsalan Iftikhar who on Monday accused Jindal of “trying to scrub some of the brown off his skin.”

“It’s foolish that MSNBC even gave somebody like this a platform,” Jindal said.

He also discussed his parents’ decision to come to America.

“We need to stop calling ourselves African Americans, Indian Americans,” Jindal said, “My parents came here over 40 years ago…. If they wanted us to be Indians, they would’ve stayed in India.”

Cavuto then asked whether he’d take anything back.

“Absolutely not,” Jindal said.
