PEGGY NOONAN: A Bombshell In The IRS Scandal.

The IRS scandal was connected this week not just to the Washington office—that had been established—but to the office of the chief counsel.

That is a bombshell—such a big one that it managed to emerge in spite of an unfocused, frequently off-point congressional hearing in which some members seemed to have accidentally woken up in the middle of a committee room, some seemed unaware of the implications of what their investigators had uncovered, one pretended that the investigation should end if IRS workers couldn’t say the president had personally called and told them to harass his foes, and one seemed to be holding a filibuster on Pakistan.

Still, what landed was a bombshell. And Democrats know it. Which is why they are so desperate to make the investigation go away. They know, as Republicans do, that the chief counsel of the IRS is one of only two Obama political appointees in the entire agency.

Hence their attack-the-messenger strategy.
