Calls for Donald Trump to release his tax returns have been gaining steam and now, they're being fueled by a million dollar bounty.
Moishe Mana, a fundraiser for Hillary Clinton, has offered to donate $1 million dollars to the charity of Donald Trump's choice if he releases his tax returns, according to The Associated Press .
"Through his financial documents, we are trying to break into the image that he's portraying to the American people," Mana said. "He says he's a successful businessman who wants to do for the country what he did for his company. Well, go ahead, show me the money."
On Wednesday, Trump's campaign manager Paul Manafort reiterated that the GOP nominee has not changed his mind.
"Mr. Trump has said that his taxes are under audit and he will not be releasing them," Manafort said.
Trump has said that if the audit is completed by Election Day, he will release them.
"If it gets finished soon, I [will] put it out immediately because there's nothing there. But until you get finished, you won't," Trump said in an interview with the AP .
Clinton's running mate Virginia Sen. Tim Kaine and Vice President Joseph R. Biden Jr. heckled the real estate mogul at the Democratic National Convention Wednesday and called on him to release his tax returns.
Even Mitt Romney, the 2012 GOP nominee, has called for Trump to release the documents. Romney, who was dogged by calls to release his own returns during his presidential run, said he doubted that would happen.
"He will never, ever release his tax returns. He has too much to hide," Romney said .
There is no law mandating that presidential candidates release their tax returns but it has been customary for candidates to release them since the 1970s.
