Then why didn't he do the same before?
That is exactly what he has done every time he has been asked. He has been very consistent in this. He has refused to single out the SwiftVets, but has pointed out repeatedly the $63 million the Dem 527's have spent, and has called for an end to all 527 ads. You may disagree with the idea of stopping the 527's, but to say he is singling out the SwiftVets is just a Dem delusion.
