Lisa Myers: "We have to worry about the culture and the integrity of the IRS"

Lisa Myers of NBC reports that the IRS  deliberately chose not to reveal that it had wrongly targeted conservative groups until after the 2012 presidential election. This implies that the IRS was picking sides in a presidential election which is a scary proposition considering the power it wields over the lives of average Americans. The New York Times reports that Treasury was aware of IRS targeting of the Tea Party in June of 2012.
The IRS commissioner "has known for at least a year that this was going on," said Myers, "and that this had happened. And did he share any of that information with the White House? But even more importantly, Congress is going to ask him, why did you mislead us for an entire year? Members of Congress were saying conservatives are being targeted. What's going on here? The IRS denied it. Then when -- after these officials are briefed by the IG that this is going on, they don't disclose it. In fact, the commissioner sent a letter to Congress in September on this subject and did not reveal this. Imagine if we -- if you can -- what would have happened if this fact came out in September 2012, in the middle of a presidential election? The terrain would have looked very different."
