WASHINGTON President Barack Obama said in an interview Sunday that he was not worried about dispelling every rumour about him - even though a recent poll showed nearly 20 percent of Americans erroneously believe he is Muslim. The facts are the facts, right? Obama told NBCs Brian Williams in New Orleans, where he was marking the fifth anniversary of Hurricane Katrina. There is a mechanism, a network of misinformation that in a new-media era can get churned out there constantly. We dealt with this when I was first running for the US Senate. We dealt with it when we were first running for the presidency. ... I will always put my money on the American people. And Im not gonna be worrying too much about whatever rumours are floating on out there. A poll released by the non-partisan Pew Research Center earlier this month showed that 18 percent of people believe Obama is Muslim - up from 11 percent in March 2009. Only 34 percent said, accurately, that he is Christian, down from 48 percent last year. Obama also defended his comments on a proposed Islamic community centre two blocks from the World Trade Centre site in New York, and said he has been consistent on the issue. I was not endorsing any particular project. I was endorsing our Constitution. And what is right, he told NBC. The media, I think, anticipating that this was going to be a firestorm politically, seemed to think that somehow there was inconsistency, and there wasnt. Citing the Constitutions freedom of religion, Obama has said that the Muslim group has the right to build the centre. So has New York Mayor Michael R. Bloomberg. The proposed centre has drawn criticism from politicians including former Alaska Governor Sarah Palin, a Republican, and Senator Harry Reid of Nevada, a Democrat.
