"And hey, are you ready for a moment of actual irony? Trump was among the choir of those urging Romney in 2012 to release his tax returns more quickly to get those headlines out of the way. Now, it’s Romney who is arguing that Trump is hiding some sort of shocking revelation in his own returns. We’ve seen the evidence that Trump gave nothing to charity, and the last time the public got a peek at his taxes he paid $0. It would also be interesting to see how Trump reported using a charity to give big gifts to himself."
