Doesn’t mean that she’s guilty of anything, of course. But it is bound to make voters wonder.

Lois Lerner, the head of the exempt organizations division of the IRS, won’t answer questions about what she knew about the improper screening – or why she didn’t reveal it to Congress, according to a letter from her defense lawyer, William W. Taylor 3rd. Lerner was scheduled to appear before the House Oversight committee Wednesday.

So: we already know Obama’s Chief of Staff knew about the targeting, but amazingly did not tell Obama (so we are told). The linked post has a link to another piece that shows Carney revealing White House involvement in orchestrating the reveal:

There was “discussion about the possibility of a speech” by Lois Lerner, who oversaw the IRS’s work on tax-exempt groups, Carney said, and conversation about testimony by the acting commissioner of the agency and “what he would say” if asked about the issue… The press secretary said the Treasury Department worked with Mark Childress, a deputy White House chief of staff.

But Obama didn’t know. That’s their story and they’re sticking with it.

Sticking with it . . . or taking the Fifth when asked more probing questions.

UPDATE: I like DaTechGuy’s take:
