Mitt Romney said there is “nothing hidden” in his tax returns that have yet to be released, responding to a question during a radio interview set to air later today regarding an onslaught of criticism from Democrats – including President Obama – on his refusal to be more transparent with his financial records.

“I don’t manage them. I don’t even know where they are,” said Romney in an interview with Iowa Radio. “That trustee follows all U.S. laws. All the taxes are paid, as appropriate.”

“All of them have been reported to the government,” said Romney, adding, “There’s nothing hidden there.”
