Donald Trump claims to have dirt on Obama, to be released Wednesday

'It's going to be very big,' billionaire tells Fox News

Donald Trump has a game-changing announcement about President Barack Obama, which he will make public on Wednesday, he told hosts of the Fox News program Fox & Friends.

“It’s going to be announced, probably on Wednesday, but I have something very, very big concerning the president of the United States,” Trump said.

Without giving any hints on exactly what this news might be, Trump told hosts Steve Doocy, Gretchen Carlson and Brian Kilmeade in a phone interview that his yet-to-be-announced news could “possibly” change the outcome of the election.

“It’s going to be very big,” Trump said. “I know you will cover it in a very big fashion.”

Trump, a Republican supporter, has been a high-profile “birther,” arguing that the president wasn’t born in the United States, despite a mountain of evidence (including a birth certificate) that proves the president was, indeed, born on U.S. soil.
