In a teleconference with pastors Tuesday, Sen. Rand Paul expressed a position on immigration that may go beyond even the controversial stand of Donald Trump. Where Trump is pushing for a temporary halt on Muslim immigration, Paul told a group of pastors he wants to hit the pause button on all immigration.

I think one thing we need to do to prevent terrorism is I think we need to have control of our borders. So I don’t think we can have an open border. … I think right now that there’s enough danger that we just need to have a temporary halt or a moratorium on immigration until we can get a better handle.

On Monday, GOP front-runner Donald Trump ignited a national and international uproar when said he wants to halt Muslim immigration until “we can figure out what’s going on.”

Rand Paul went on to explain the rationale for his own position:

Almost every terrorist attack we’ve had so far has included legal immigration from certain countries. This woman [in San Bernardino] came through Saudi Arabia and Pakistan on a fiancé visa. The Boston bombers came here on a refugee visa. The two Iraqi potential bombers that came to my hometown in Kentucky came here on refugee visas. The 9/11 hijackers, all 19 of them, came on visas.

And so, what we need to do is we need to have a better vetting system of who’s coming. So I want to have a 100% entry and exit knowledge, and once we have that then I think we can restart normal immigration. But for a while I would just push pause and say we’re going to slow it down for now. People say, “Well, gosh, that’s not fair.” Well, nobody really has a right to come to our country. It’s a privilege and an honor to let people come to our country.

The GOP candidate noted there’s historical precedent for such action. Before World War II roughly a million people a year were coming into our country, but during the war that number fell to about 24,000 a year.

The teleconference with pastors was hosted by Randy Robison, co-author of Paul’s new book Our Presidents and Their Prayers and son of The Stream‘s publisher James Robison. The pair touched on several topics, including the President’s Oval Office speech, the state of the primary race, abortion funding and the importance of faith in the public square. “We shouldn’t be embarrassed to say we are a religious nation,” Paul said, “and shouldn’t be embarrassed to say we’re a Christian nation.”

Last year, Paul put forward an amendment in the Senate that would prohibit foreign aid from going to nations that persecute Christians. The United States government gives $30 billion a year to countries that put people to death for converting to Christianity, for criticizing the state religion or for marrying someone of another faith. Paul thought his amendment would be a slam dunk, but the amendment failed in committee 18-2.

This boggles my mind because as I travel the country and in speech after speech I’ll ask people if we should stop sending money to countries that hate us and persecute Christians and to a person, I have not yet met a person outside of Washington who’s for this. And yet the vast majority of official Washington is still for giving unlimited money to countries that hate us.”
