Mitt Romney responded to attacks from President Barack Obama and his Democratic allies who have suggested he's hiding details about his personal finances, calling the accusations nothing more than an attempt to distract voters.

In an interview with Radio Iowa's O. Kay Henderson, the Republican nominee insisted he has little to do with his personal investments because they are managed by a blind trust.

"I don't manage them," Romney said. "I don't even know where they are."

Responding to reports that some of his investments have been overseas, Romney insisted his "trustee follows all U.S. laws." He added: "All the taxes are paid, as appropriate. All of them have been reported to the government. There's nothing hidden there."

He accused Obama of trying to distract from his economic record.

"The president is going to try to do anything he can to divert attention from the fact that his jobs record is weak, and he has no plans to make things better," Romney said.

Romney's response was similar to what he said during the Republican primary when he came under attack from GOP rivals who called on him to release years of tax returns—a message that Obama and his allies have repeated in recent days. Back then, the former Massachusetts governor eventually caved, releasing returns dating back to 2010.

But Romney has so far resisted calls to release additional information about his personal finances, rejecting the approach of his father, George, who released 12 years of returns when he ran for president in 1964.
