Were the IRS to stop obstructing the investigation maybe we could prove that the records were deliberately leaked and who leaked them. Instead they say, this is just a single (rogue) person, not a problem, no investigation is needed. I don't expect the IRS to admit wrongdoing, though from an integrity standpoint it would be nice, but I do expect them to stop obstructing the investigation and for the President to take action to make the obstruction stop.
