Mitt Romney’s GOP rivals have been hammering him about releasing his income tax numbers even after he promised to make them public in April, but during CNN’s GOP debate he had quite a talking point saying, “I’m not going to apologize for being successful,” to which he explained that he doesn’t want to give President Obama any early ammunition.

Former New Hampshire Governor John Sununu, who has been campaigning with Romney in South Carolina, joined America’s Newsroom to discuss this issue. Sununu thinks this shouldn’t even be an issue because all four of the GOP candidates have decided to not release theirs as well.

Specifically, he explained why people should worry about Newt Gingrich’s ethics problems instead, saying, “Three out of four Republicans on that ethics committee voted against Mr. Gingrich and the issues were so bad that his own leadership kicked him out of the leadership and it’s important to note that Nancy Pelosi was one of the members of that group that has those records on file and whatever Nancy Pelosi knows, Barack Obama knows, so Newt Gingrich better release that now … so the voters know what they know.”
