In January, Donald Trump had this to say when he was asked about whether he would release his tax returns: "I have very big returns, as you know, and I have everything all approved and very beautiful and we'll be working that over in the next period of time."

Yet he held off on releasing his returns. And on Tuesday night, the presumptive Republican presidential nominee seemed to close the door for good on the matter. He told the Associated Press that he wouldn't release his returns before the November elections unless what he described as Internal Revenue Service audit of his finances was complete.

"There's nothing to learn from them," Trump said of his tax returns.

That prompted Mitt Romney to take Trump to task late on Wednesday afternoon.
