Donald Trump is an unhappy bigot who will do all that he can to ensure that President Obama doesn't get re-elected. He says that he will be revealing a secret tomorrow that could severely tarnish Obama's image.

David Letterman said that Trump is racist. Today, the bitter reality star continues to prove that he is. Donald says that his big reveal "could swing the election" and the news is "gigantic."

The reality star will post the news tomorrow on Twitter, Fox News reports.

The only hints we have is that the news is “something very, very big concerning the president of the United States. It's going to be very big."

He believes that his "large, borderline gigantic news" could "possibly" swing the election.
