If you'll check the facts, you'll find the tax returns for 2011 state that the Obama's contributed 22% of their income to charity. President Obama also contributed his $1,000,000 Nobel Peace Prize to charity. Of course, we don't know what Mitt Romney's contributions were for 2011 since he has not released his tax returns.

When is Mitt Romney going to release all his tax returns? His own father started the practice in 1968 releasing 13 years worth. President Obama released seven years of tax returns in 2008 and every year since then.
Romney has never released tax returns, not when he ran for senate in 1994, not when he ran for governor in 2002. What is he hiding? Why the foreign bank accounts?
