On Sunday, Republican presidential candidate Ben Carson told viewers of NBC’s "Meet the Press" that he would “not advocate that we put a Muslim in charge of this nation.” Yesterday, he told Fox News viewers that he has seen a spike in donations in the days since that declaration.

“The money has been coming in so fast, it’s hard to even keep up with it,” he said. “I remember the day of the last debate, within 24 hours we raised $1 million. And it’s coming in at least at that rate, if not quite a bit faster.”

And a super PAC created to raise money for Carson, The 2016 Committee, told The Washington Times that it has seen a similar increase in funding. “We sent out an e-mail to Carson supporters, and we’ve never had an e-mail raise so much money so quickly—it’s unbelievable,” said John Philip Sousa IV, who chairs the super PAC. “My phone has exploded over the last 48 hours—of people wanting me to pass on to Dr. Carson how much they respect his truthfulness and believe in the American system, and how absolutely not should anyone who believes in Sharia law come close to the White House. The people are on Dr. Carson’s side on this one—sorry NBC you lose.”

Carson elaborated on his stance against a Muslim leader of the free world via a Facebook post on Monday, which read, in part:

I meant exactly what I said. I could never support a candidate for president of the United States that was Muslim and had not renounced the central tenant of Islam: Sharia Law. Those Republicans that take issue with my position are amazing. Under Islamic Law, homosexuals–men and women alike–must be killed. Women must be subservient. And people following other religions must be killed. I know that there are many peaceful Muslims who do not adhere to these beliefs. But until these tenants are fully renounced…I cannot advocate any Muslim candidate for president.

During an interview with Sean Hannity the same day, he said, “If someone has a Muslim background and they’re willing to reject those tenets and to accept the way of life that we have and clearly will swear to place our Constitution above their religion…I would then be quite willing to support them.”
