Republican presidential candidate Ben Carson says Islam is antithetical to the Constitution, and he doesn't believe that a Muslim should be elected president.
Carson, a devout Christian, says a president's faith should matter to voters if it runs counter to the values and principles of America.
Responding to a question during an interview broadcast Sunday on NBC's "Meet the Press," he described the Islamic faith as inconsistent with the Constitution.
"I would not advocate that we put a Muslim in charge of this nation," Carson said. "I absolutely would not agree with that."
He did not specify in what way Islam ran counter to constitutional principles.
Carson's comments came amid lingering fallout over Republican Donald Trump's refusal last week to take issue with a man during a campaign event who wrongly called President Barack Obama a Muslim and said Muslims are "a problem in this country."
In the NBC interview, Carson said he believes that Obama was born in the U.S. and is Christian, saying he has "no reason to doubt" what the president says.
Carson also made a distinction when it came to electing Muslims to Congress, calling it a "different story" from the presidency that "depends on who that Muslim is and what their policies are, just as it depends on what anybody else says."
"If there's somebody who's of any faith, but they say things, and their life has been consistent with things that will elevate this nation and make it possible for everybody to succeed, and bring peace and harmony, then I'm with them," Carson said.
Congress has one Muslim member, Democratic Rep. Keith Ellison of Minnesota.
