Republican presidential front-runner Donald TrumpDonald TrumpLaw professors file misconduct complaint against Conway: report State Dept. memo — on dangers of leaks — leaks to media Trump: FBI ‘totally unable’ to stop leaks MORE lashed out at Mitt Romney Wednesday night, shortly after the GOP's 2012 presidential nominee went after him for not releasing his tax returns.

The business mogul called Romney a "fool" and accused him of trying to play "tough guy."
 
 
 
 
Earlier Wednesday, Romney suggested that Trump had not released his tax records because he has something to hide.

"Frankly, I think we have a good reason to believe that there's a bombshell in Donald Trump's taxes," the 2012 Republican nominee said in an interview with Fox News.
 
"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."
