US President Barack Obama said he is not worried about a recent poll showing that nearly a fifth of Americans believe he is a Muslim -- up from just a tenth who believed the same thing in March 2009.
"The facts are the facts," said Mr Obama, who is a Christian.
The president blamed the confusion on "a network of misinformation that in a new media era can get churned out there constantly".
Asked about persistent accusations that he was not born in the United States, the president responded: "I can't spend all my time with my birth certificate plastered on my forehead."
