(CNN) – Despite the long form birth certificate released by the White House Wednesday, real estate mogul Donald Trump said "I don't make up anything" when asked about his recent claim that the president's birth certificate was missing. Still, he is undecided about paying for the sleuths he sent to Hawaii.

In an interview airing Wednesday on CNN's "John King, USA," Trump said he can now recall investigators he'd sent to Hawaii to look into President Obama's birth.

"Would I pay them? I don't know," he said. "I can say this, let me just tell you, I don't make up anything…I have done a great service to the American people."

When pressed on his role in stirring up birther controversy by CNN's Chief National Correspondent John King, Trump downplayed his actions saying, "Excuse me, every time I sit down with the press all they want to talk about is the birth certificate and I got him to do something that nobody else could get him to do and I take great credit for that."

And though the possible presidential candidate, currently in the first-in-the-nation primary state of New Hampshire for several appearances, says he hasn't seen the long form birth certificate, Trump now hopes "a lot of experts will analyze it."
