There"s "a network of misinformation that in a new media era can get churned out there constantly," Obama said in an interview Sunday with NBC in New Orleans after marking the fifth anniversary of Hurricane Katrina.
"I can"t spend all my time with my birth certificate plastered on my forehead," Obama said.
"The facts are the facts. We went through some of this during the campaign - there is a mechanism, a network of misinformation that in a new media era can get churned out there constantly," said a visibly annoyed Obama, referring to "birthers," who keep questioning either the existence or the validity of his Hawaiian birth certificate.
A stunning 18 percent of Americans still identify Obama as Muslim, according to a Pew poll released earlier this month. Only a third identified Obama as Christian and 43 percent said they didn"t know his faith.
