Donald Trump in $5m challenge to President Obama

DONALD Trump, the outspoken US property developer, has vowed to give $5million to charity if Barack Obama releases his college and passport records.

Mr Trump, whose Aberdeenshire golf development was the subject of a hard-hitting BBC documentary earlier this week, is a vocal critic of the US president.

Last year he questioned whether Obama was born in the US and therefore eligible to be president, later taking the credit for the publication of his long-form birth certificate.

The US Apprentice star has used his Twitter page to comment upon the US presidential race, and he had promised a “big Obama announcement” to his 1.7m followers.

But far from any revelation which could derail the president’s re-election campaign, Mr Trump’s announcement was completely of his own making.

In a video posted on his YouTube channel, Mr Trump made the promise to give a fraction of his fortune to a charity of President Obama’s choosing.

“If Barack Obama opens up and gives his college records and applications and his passport records and applications, I will give a charity of his choice – inner-city kids in Chicago, American Cancer Society, Aids research, anything he wants – a cheque, immediately, for $5m,” he said.

“The cheque will be given one hour after he releases the records so stated.”

The New York-based mogul considered running for the presidency before endorsing Mitt Romney in Las Vegas earlier this year.

Mr Trump gave a deadline of 5pm on 31 October for the release of President Obama’s records.
