"Frankly, I think we have a good reason to believe that there's a bombshell in Donald Trump's taxes," the 2012 GOP nominee told Fox News on Wednesday.
"I think there's something there. Either he's not anywhere near as wealthy as he says he is or he hasn't been paying the kind of taxes we would expect him to pay, or perhaps he hasn't been giving money to the vets or to the disabled like he's been telling us he's doing."
Romney said it's suspicious that every time Trump is asked about his taxes, he "dodges" and "delays."
He added that Trump likes to "tell people how well he's done," but has not yet let people look at his taxes.
"We're talking about taxes already filed, back taxes. And my back taxes, when I ran in 2012, my back taxes I put out in January of 2012," he said.
