Which of the following excuses has Mitt used as he's tried to release as little of his tax returns as possible?

A. I'm waiting until I'm elected president
B. My accountant isn't available to release them
C. It's not about my tax rate, it's about the tax rate of the American people
D. "I want to make sure I beat Barack Obama"

If you guessed all of the above, you're correct. Yesterday, Mitt dropped the excuses long enough to release one year's worth. One year.

His disclosure revealed a previously hidden Swiss bank account that was shut down in 2010 after an adviser reportedly realized it was politically problematic.

Between the old Swiss bank account, the Cayman Islands investments, and other tax-minimizing tactics, he paid just 13.9 percent on the $22 million he made in 2010—about half the rate most middle-class Americans pay. And under the tax plan he'd put in place as president, he'd pay even less.

But here's the thing: We still don't know what tax rate he's paid in past years, or if he's used tax loopholes that are only for the very wealthy, because he won't share any more of his returns.

When Mitt's own father, George Romney, ran for president in 1967, he released 12 years of returns, saying "One year could be a fluke, perhaps done for show."

American voters deserve to know how he makes his money, where he invests it, and the larger story that tells about his values.

Sign our petition, and tell Mitt it's time to step up and release the rest of his tax returns.
