Mitt Romney addressed mounting pressure for him to release additional years of tax returns on Tuesday, telling National Review Online that he was not eager to give the Obama campaign more fodder for attacks.

"In the political environment that exists today, the opposition research of the Obama campaign is looking for anything they can use to distract from the failure of the president to reignite our economy," Romney said. "I’m simply not enthusiastic about giving them hundreds or thousands of more pages to pick through, distort, and lie about."

Romney has been adamant in his refusal to release more returns. During a rare network television appearance last Friday, he said he would only be releasing one more year of tax returns.
