Donald TrumpDonald John TrumpDems flip Wisconsin state Senate seat Sessions: 'We should be like Canada' in how we take in immigrants GOP rep: 'Sheet metal and garbage' everywhere in Haiti MORE says the reason he can't release his tax returns is because he's being audited.

"I want to release my tax returns, but I can't release it while I'm under an audit," Trump said Thursday night at the CNN Republican debate. "We're under a routine audit. I've had it for years, I get audited. And obviously if I'm getting audited, I'm not going to release a return."
"I think people will understand that."
The billionaire GOP front-runner was responding to a question about Mitt Romney's suggestion that there is a "bombshell" in his tax returns.
Trump says the 2012 Republican nominee "looked like a fool" for not releasing his returns until late in the campaign cycle, but insists the auditing of his own tax returns is legitimate excuse for holding back their release.
"As soon as the audit is done," Trump said, "I love it."
