His proposal also appears to be the final straw for Arianna Huffington and the Huffington Post. The editor-in-chief penned an editorial piece on Monday retracting the paper's initial decision to cover Trump's campaign in its entertainment section.
"Now that Trump, aided by the media, has doubled down on the cruelty and know-nothingness that defined his campaign's early days, the 'can you believe he said that?' novelty has curdled and congealed into something repellent and threatening — laying bare a disturbing aspect of American politics," Huffington wrote. "We believe that the way we cover the campaign should reflect this shift. And part of that involves never failing to remind our audience who Trump is and what his campaign really represents."
Other critics of Trump's proposal took to Twitter to blast the presidential candidate.
The Republican presidential candidate likened his proposal to ban Muslims from entering the United States to policies implemented by former U.S. President Franklin Roosevelt against people of Japanese, Germans and Italian descent during World War II.
"What I'm doing is no different than FDR," Trump said on ABC's "Good Morning America" program on Tuesday in one of a round of heated television interviews where he defended his plan in the wake of last week's California shooting spree by two Muslims who authorities said were radicalized.
"We have no choice but to do this," he told ABC. "We have people that want to blow up our buildings, our cities. We have figure out what's going on."
