Er, I thought everyone knew by now that story was a bs fabrication of the right-wing media?
No, but I can understand why folks would want to spread that line. Here's an excerpt of the latest news on the subject:
The Oversight Committee .... is expressing gross dissatisfaction with Wilkins’s testimony and, in a letter sent to him on Wednesday, offering him the opportunity to amend it. “In your testimony, you stated ‘I don’t recall’ a staggering 80 times in full or partial response to the Committee’s questions,” committee chairman Darrell Issa and Ohio representative Jim Jordan wrote. “Your failure to recollect important aspects of the Committee’s investigation suggests either a deliberate attempt to obfuscate your involvement in this matter or gross incompetence on your part.”
The most pertinent subject on which Wilkins’s memory failed him was the nature of his communications with Treasury Department officials: in particular, whether he discussed the applications of tea-party groups with anybody at the Treasury Department, whether he discussed with Treasury Department officials regulatory guidance for 501(c)(4) entities engaged in political activities, and whether he discussed with them the inspector general’s report that blew the lid off of the targeting scandal in mid May.
"I don't recall" is how you prevent later perjury charges when you're on the wrong side of an investigation and you're doing your best to cover your ass while not advancing the investigation. But you probably knew that.
