Rep. Trey Gowdy (R-SC) honed in on evasive answers by former IRS Commissioner Douglas Shulman at the House Oversight and Government Reform Committee hearing into the IRS scandal Wednesday. Shulman refused to answer "yes" or "no" when Gowdy asked him whether he had taken any action to investigate or stop the targeting of conservative groups when he was made aware of it in May 2012. Instead of answering, Shulman claimed that he had been satisfied that the Inspector General was investigating, and said that he had merely been following practices left in place by his predecessor at the IRS.
