I only saw Pfeiffer on Fox, and wasn't clear on what he was claiming Issa knew. Knowing there was an IG investigation into targeting claims isn't the same as knowing that conservatives were in fact being targeted. My guess is that's going to be the distinction with Issa.
Regardless, I'm not sure what the WH is trying to imply regarding Issa. He's not in charge of the IRS. He had long called for investigations into the targeting claims. If he had no first hand knowledge of targeting and was only aware of an investigation then he acted appropriately. It's to be expected that he had a heads up on an investigation because of his oversight authority. Lots of people knew there was an IG investigation into the targeting claims. Heck, Jack Lew said it was published on a govt. web site.
The White House claims specifically regarding the knowledge of the IG investigation (only informed a few weeks ago) strain credulity. We now know that senior Treasury officials and Obama's appointee to the Chief Counsel of the IRS all had knowledge of the targeting conservatives approximately 1-2 years before the IG investigation began. That this knowledge was not shared with the WH is hard to believe.
Agree completely. Like you said, Issa is not in charge of the IRS. Just more of their distraction/shell games.
