Ann Romney defended her husband’s refusal to release more than a single year of his tax returns this morning, telling ABC’s Robin Roberts that her husband Mitt has “given all you people need to know” about the Romney family finances.

The statement came after Ann attempted to defend Mitt by using the same logic as Texas Senator Kay Bailey Hutchison: that Romney gives money to the Mormon Church, so of course there’s nothing bad in his tax returns.

“He’s a very generous person. We give ten percent of our income to our church every year. Do you think that is the kind of person who is trying to hide things, or do things?” Ann Romney asked Roberts. “No. He is so good about it. Then, when he was governor of Massachusetts, didn’t take a salary for four years.”

“Why not show that, then?” Roberts asked. Ann responded to that question by borrowing Mitt’s favorite defense: If he released the returns, the Obama campaign would scrutinize them (which is, of course,  the whole purpose of releasing financial records — transparency to the press, the opposition, and above all the public.)

“Because there are so many things that will be open again for more attack… and that’s really, that’s just the answer,” Romney replied to Roberts. “And we’ve given all you people need to know and understand about our financial situation and about how we live our life.”

It’s worth pointing out that the American people still think that they need to know more. According a new USA Today poll,  54 percent believe that Mitt Romney should release additional tax returns.
