His remarks now another distraction for the republican party. Nbcs Holly Jackson joins us with more. Good evening, tamron. Ben carsons campaign tells me he probably will reach out to members of the Muslim Community, as tonight theres new fallout from those comments, with one Group Calling on carson to drop out of this race altogether. From a typically softspoken candidate, a response making lots of noise today, after ben carson was asked on meet the press whether a president s faith should matter to voters . If it fits within the realm of america and consistent with the constitution, i have no problem. So you believe that islam is consistent with the constitution . No, i dont i do not. I would not advocate that we put a muslim in charge of this nation. I absolutely would not agree with that. The comments, seizing the spotlight in the republican race. The constitution provides that there should be no religious test for public office. And im a constitutional. Reporter article 6 states no religious test shall ever be required as a qualification to any office. That clause cited by Muslim American advocates who are now calling on carson to withdraw from the race. It shouldnt be just american muslims who are calling for mr. Carson to withdraw, or at least to repudiate these kinds of unamerican comments. It should be our nations political and religious leaders, from all parts of the political spectrum. Reporter carsons Campaign Today clarifying his remarks. Saying, while carson has Great Respect for the Muslim Community and believes the muslims should be allowed to run, he just doesnt believe the American People are ready for that. Just last week donald trump didnt denounce a questioner who called muslims a problem in the u. S. Today elaborating. I have friends that are muslims. Theyre great people, amazing people. But, we certainly do have a problem. I mean you have a problem throughout the world. Whats the problem . Well, you have radicals that are doing things. I mean, it wasnt people from sweden that blew up the world trade center, jake. Reporter trump, still the gop frontrunner after last weeks debate, according to an nbc Online Survey but he didnt pick up much support. Carly fiorina did, emerging as the clear winner. And in a different poll taken before he made his controversial remarks today, ben carson dropped five points. These now the top tier stangds. The rest of the field barely registering. Some republican candidates, when asked about a potential muslimamerican president , pointed out it would ultimately be up to the voters to make that decision. And according to a poll out this summer, 60 of americans say they would back a muslim candidate. Theres less support among republicans. 45 . Tamron . All right, hallee, thank you very much.
