(CNN)- Obama campaign senior adviser David Axelrod said Republican presidential candidate Mitt Romney "has a penchant for secrecy" and is holding himself to a different standard by not releasing more years of tax returns.
Following criticism and allegations from Democrats suggesting that the presumptive GOP nominee had not been paying taxes, Romney said Thursday that he has paid no less than 13% in personal income taxes over the past ten years.

"I'll say he's setting an entirely new precedent," said Axelrod when asked by CNN's Piers Morgan if he believes Romney has paid at least a 13% tax rate.
"Governor Romney thinks he can operate under a different set of rules," said Axelrod, noting the precedent set by Romney's father who released 12 years of tax returns in his unsuccessful run for the White House in 1968. "He has a sense of entitlement that he doesn't have to operate under the same set of rules that presidential candidates have for decades."
