Donald Trump on Thursday said he has investigators in Hawaii examining President Obama's citizenship, as the real estate mogul continues to drum up noise for a possible 2012 presidential run.
"I have people that actually have been studying it and they cannot believe what they're finding," Trump said Thursday on NBC's "Today."
Trump, 64, has become a leading voice for the "birthers" over the past few weeks, ramping up allegations that the president wasn't born in this country and doesn't have a birth certificate. Still, Trump says he hopes Obama can produce a birth certificate.
The president's administration released a "certificate of live birth" from Hawaii in 2008, but Trump says it's not proof Obama is a U.S. citizen.
In an NBC/Wall Street Journal poll Wednesdayof potential 2012 Republican nominees, Trump tied for second place with former Arkansas Gov. Mike Huckabee, with former Massachusetts Gov. Mitt Romney coming on top. Trump said he'll make his decision by June on whether to run.
A rep for Trump didn't return calls for comment.
