NEW YORK (AP) — Donald Trump wants to make a deal with President Barack Obama.

If Obama releases his college and passport records by the end of October, the New York real estate mogul and reality show host says he will contribute $5 million to a charity of the president's choice.

Trump made the offer Wednesday in a video posted to his Twitter account. He called Obama "the least transparent president in the history of this country," and said that by taking the deal Obama would satisfy voters' questions about his past.

Trump drew broad publicity last year for questioning whether Obama was born in the U.S. and eligible to be president. Obama later released his long-form birth certificate showing that he was born in Hawaii in 1961. In the video, Trump said he was proud to have pushed Obama to release the birth certificate or "whatever it may be."

Trump has endorsed Republican Mitt Romney for president. Obama campaign spokeswoman Jennifer Psaki declined to comment on the Trump video, saying "given Trump is one of his biggest supporters, this is a question best directed to the Romney team in Boston."
