In an interview with NBC News, Trump was asked if a database tracking Muslims in the country was something he would implement if elected president.
"Should there be a database system that tracks the Muslims here in this country?" the NBC News reporter asked Trump.
"There should be a lot of systems, beyond database [sic], we should have a lot of systems, and today you can do it," Trump replied. "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."
"But that’s something your White House would like to implement?" the reporter subsequently asked.
“I would certainly implement that. Absolutely,” Trump said.
Trump subsequently tweeted that he never called for such an idea, and that the NBC reporter imposed it on him.
"Part of why we are great already, Mr. Trump, is because we have the most unusual ability to bring people here and turn them into Americans," she said.
Ted Cruz, who has mostly stayed away from engaging Trump this election season, rejected the idea of registries as a whole, saying they violated First Amendment rights, according to Politico.
He specifically noted that singling out Muslims would be a “dangerous” precedent. “I don't think it's a good idea to treat anybody differently,” he said in New Hampshire after filing for the state's primary. ”One of the hallmarks of America is that we treat everybody the same. So if we are just going to pick out a particular group of people based on religion, based on their race, based on some other thing, that's setting a pretty dangerous precedent I believe.”
