Trump: Ban all Muslim travel to U.S.

(CNN)Republican presidential front-runner Donald Trump called Monday for barring all Muslims from entering the United States.

Trump, who has previously called for surveillance against mosques and said he was open to establishing a database for all Muslims living in the U.S., made his latest controversial call in a news release. His message comes in the wake of a deadly mass shooting in San Bernardino, California, by suspected ISIS sympathizers and the day after President Barack Obama asked the country not to "turn against one another" out of fear.

"Without looking at the various polling data, it is obvious to anybody the hatred is beyond comprehension. Where this hatred comes from and why we will have to determine," Trump said in a statement. "Until we are able to determine and understand this problem and the dangerous threat it poses, our country cannot be the victims of horrendous attacks by people that believe only in Jihad, and have no sense of reason or respect for human life."

Trump's comments are likely to roil the Republican presidential race, forcing many of his opponents for the nomination to engage in a debate over whether there should be a religious test to enter America. But they may do little to dent Trump's own popularity among Republican primary voters. The billionaire businessman has dominated the GOP contest for months despite repeated controversies that would likely sink other White House hopefuls.

Trump's campaign added in the release that such a ban should remain in effect "until our country's representatives can figure out what is going on."

The release pointed to an online poll from the controversial Center for Security Policy, which claimed that a quarter of Muslims living in the U.S. believe violence against Americans is justified as part of a global jihadist campaign. Critics have questioned the reliability of the organization's information. It also pointed to a Pew Research poll, which the campaign declined to identify, which the campaign claimed points to "great hatred towards Americans by large segments of the Muslim population."

Trump campaign manager Corey Lewandowski told CNN on Monday that the ban would apply not just to Muslim foreigners looking to immigrate to the U.S., but also to Muslims looking to visit the U.S. as tourists.

"Everyone," Lewandowski said when asked if the ban would also apply to Muslim tourists.

"Great surveillance and vigilance must be adhered to," said Trump in an additional statement Lewandowski provided to CNN. "We want to be very fair but too many bad things are happening and the percentage of true hatred is too great. People that are looking to destroy our country must be reported and turned in by the good people who love our country and want America to be great again."

Lewandowski declined to answer multiple questions about what the shutdown on Muslim immigration would mean for Muslim Americans and Muslims already living in the U.S. legally.
