Former Justice Department attorney J. Christian Adams says the Donald Trump administration could reinstate a national registry for immigrants coming to the U.S. from countries with significant Muslim populations.

On "The Kelly File" tonight, Adams argued that it's a "reasonable request" that people from hotbeds of terrorism are subject to additional screening.

"It's neither 'Muslim' nor a 'registry.' It's where terror is," he stated.

He pointed out that some of the 9/11 terrorists overstayed their visa in the U.S., arguing that a tool like this could have helped prevent 9/11.

"You can impose entry requirements that will protect this country by asking them about their views of certain issues," Adams explained. "Do they think it's legitimate to wage jihad against the West?"

Megyn asked if Trump can reinstate this policy unilaterally or if he has to go through Congress.

"He can do it with a stroke of a pen," Adams said. "And I suggest he probably is going to do it, because that's why he was elected, to try and keep America safer."
