Presumptive Republican presidential nominee Mitt Romney on Thursday insisted that he had paid more than 13 percent of his income in taxes — or more if donations to the Mormon church are included — over the last 10 years, and accused the people who want to see his returns of being “small minded.”

During a press conference at the airport in Greer, South Carolina, the GOP hopeful told reporters that he couldn’t understand why people keep asking about his taxes.

“I just have to say, given the challenges that America faces — 23 million people out of work, Iran about to become nuclear, one out of six Americans in poverty — the fascination with taxes I paid I find to be very small minded compared to the broad issues that we face,” Romney explained.
