Meanwhile, Donald Trump took calls for a religious test on incoming refugees one step further, when an NBC reporter asked whether Trump would implement a database to track all American Muslims.

Donald Trump: “There should be a lot of systems, beyond databases. I mean, we should have a lot of systems. And today you can do it. But right now, we have to have a border, we have to have strength, we have to have a wall. And we cannot let what’s happening to this country happen any longer.”

NBC reporter: “But that’s something your White House would like to implement?”

Donald Trump: “Oh, I would certainly implement that. Absolutely.”
