Trump Threatens Obama "Bombshell"

Donald Trump claims that he's going to drop a "bombshell" on President Obama tomorrow.

“Something very, very big concerning the president of the United States,” he said. “It’s going to be very big. I know one thing — you will cover it in a very big fashion.” Trump, who said he will announce the news on Twitter “sometime probably Wednesday,” suggested it could “possibly” impact the election. The businessman, who considered a run for the White House but endorsed former Gov. Mitt Romney, has long been a high-profile Obama birther conspiracy theorist.
