Eric Fehrnstrom: Mitt Romney Tax Returns 'Not An Issue' (VIDEO)

Mitt Romney advisor Eric Fehrnstrom brushed off inquiries into the presumptive Republican presidential nominee's tax returns Sunday, telling CNN that “taxes are not an issue."

"Mitt Romney has said he'll put out two years of tax returns, he put out his 2010 return, hundreds of pages of tax return information that’s on the website," Fehrnstrom said on "State of the Union."

"He’ll put out his 2011 returns once it's complete and filed," he said. "He's had financial disclosures going back to 2002 when he was governor of Massachusetts, those too can be found on Mitt Romney's website."

While Romney has released tax returns from 2010 and estimates from 2011, members of both parties have urged him to make a more comprehensive disclosure.

Those calls have been amplified in recent weeks after Senate Majority Leader Harry Reid (D-Nev.) told The Huffington Post in an interview that a Bain Capital investor told him that Romney "didn't pay any taxes for 10 years."
