Donald Trump surrogate Carl Higbie and CAIR Florida leader Hassan Shibly got heated tonight on "The Kelly File" while discussing a proposed "Muslim registry."

Members of Trump's team have suggested that the new administration could reinstate a national registry for immigrants from countries with significant Muslim populations.

Higbie said he supports the proposal because protecting Americans is of the utmost importance.

He argued that increasing the screening of people coming from hotbeds of terrorism is an effective way to accomplish that.

"Have you no sense of decency, sir?" Shibly asked. "Freedom of religion is a fundamental principle that I've taken an oath - I'm sure you've taken an oath - to protect. And it is ineffective to target people simply based on religion."

He added that anyone coming into the U.S. should face scrutiny and screening, but it shouldn't be heightened based upon their religion or country of origin.

Higbie reiterated that Trump's first priority is keeping Americans safe, and he's committed to thoroughly screening people who want to come to the U.S.

"I welcome immigrants. I welcome people from all over the world to join us here. But I want to make sure that it's safe for Americans in my country that I fought for."
