Mitt Romney says he'll release multiple years of his tax returns -- but not before South Carolina votes on Saturday.

The former Massachusetts governor says his 2011 taxes aren't ready to release yet.

During Thursday night's GOP debate, Romney defended his decision not to release any of his previous tax returns by saying that releasing them one by one will help President Barack Obama.

Romney says he'll release his returns all at once, but isn't saying how many years' worth.

Romney rival Newt Gingrich released his tax returns midway through Thursday's debate -- and he's criticizing Romney's stance, saying that South Carolina voters deserve to see Romney's return before they vote.
