(CNN) – Possibly-serious Republican presidential candidate Donald Trump is giving few details about the investigation he claims to have launched in Hawaii to get to the bottom of where President Obama was born, but the business mogul told CNN Thursday Americans will be "very surprised" by what he has found.
"We're looking into it very, very strongly. At a certain point in time I'll be revealing some interesting things," Trump said on CNN's American Morning.
Trump first claimed earlier this month he had sent investigators to Obama's home state in an effort to find out if the president was indeed born there, as he says he was and several media organization's independent investigations have confirmed.
"I have people that have been studying it and they cannot believe what they're finding," Trump told NBC then.
But Trump has since offered few details about the on-the-ground investigation and, in the interview with CNN Thursday, wouldn't specifically say if it had uncovered new details.
"You'll be very surprised," he said when asked by CNN's Ali Velshi if his investigators have found anything.
During the interview with CNN, Trump also maintained he is worth considerably more than the $2.7 billion Forbes Magazine has estimated, and says he will reveal the real number if he decides to run for president.
I can tell you that's a very low number," Trump said of the Forbes estimate. "It's much more than that. And if I decide to run, which I very well may surprise people, but if I decide to run, I will give a net worth statement essentially. As you know, we have to fill out very detailed forms for the federal government. And I think people will be extremely impressed."
