So there are people who truly believe that the IRS was being investigated for something it had been accused of doing for well over a year, that was highly political, and in an election year, and nobody in the White House knew what it was about? And that it wouldn't be shared with the POTUS?Really?
The burden of proof isn't on the President to prove he doesn't know anything. The burden of proof is to prove he knew something. I don't think people realize how many audits the government does on a yearly basis and to expect the President to stay abreast of it would be insane. And considering this is the umpteenth time that Obama has been accused of knowing something and most of them have been unsubstantiated, the Right has little credibility in arguing that Obama must have known something.
ETA: And even beyond that, just b/c he knows a possible investigation is ongoing, is he suppose to disclose all investigations? How many investigations and allegations are unfounded? Isn't the point of an investigation to let it run its course?
