The Donald’s Apprentice?

Donald Trump shaves the head of wrestling impresario Vince McMahon during WrestleMania 23 April 1, 2007.

Only Donald Trump can seemingly turn an act of charity into the plague.

The single largest contributor to the Donald J. Trump Foundation — as listed on 990 forms filed with the Internal Revenue Service — is denying it gave $5 million to the coiffed one.

World Wrestling Entertainment, which now just goes by the WWE, distanced itself Wednesday from Trump, amid The Donald’s promise to pay $5 million to the charity of President Obama’s choice if the commander-in-chief releases all of his college and passport records.

As much as the Stamford-based branding machine likes to say it’s a publicly-traded company, the WWE is Vince and Linda McMahon, the latter of whom is pitted in a tight race for the U.S. Senate in Connecticut.

The press shop at the WWE didn’t do the wrestling matriarch any favors, however.

“WWE has not made any donation to the Donald J. Trump Foundation,” WWE’s Brian Flinn told Hearst Newspapers Wednesday evening. “However, as I understand it, the Vince and Linda McMahon Family Foundation has donated $5 million in total to the Donald J. Trump Foundation.”

Flinn said that Trump’s foundation had incorrectly filled out its IRS-990 forms and that the WWE would be contacting “The Apprentice” star to remedy the error.

A spokesman for McMahon’s campaign denied that the candidate or her husband, who succeeded her as the company’s chief executive in 2009 when she first ran for the Senate and lost, gave to Trump’s charity.

The Smoking Gun website was the first to report that WWE was the top contributor to Trump’s foundation, characterizing the man who fancied himself as presidential material as a cheapskate.

WWE did confirm to Hearst that it paid Trump $1 million to appear in 2007 during its marquee event, WrestleMania 23, where The Donald shaved Vince McMahon’s head in the ring.

UPDATE: The WWE clarified Thursday that Vince McMahon indeed gave $5 million to Trump, not the company or the couple’s foundation.

The “birther” angle probably doesn’t play too well in blue Connecticut, which is poised to be in the win column again for Obama, who won the state by 22 points four years ago.

Despite the McMahons giving $150,000 to the pro-Mitt Romney super PAC Restore Our Future, McMahon’s campaign recently released a television ad encouraging Democrats and unaffiliated voters to split their ballot for the Republican Senate nominee and Obama.
