The IRS scandal has claimed its first scalp. Steve Miller, the acting commissioner of the Internal Revenue Service, has resigned after being asked to do so by the Treasury secretary, President Obama announced in a late-afternoon statement to the media. The agency was found to have inappropriately targeted conservative groups’ applications for tax-exempt status. “Americans are right to be angry about it,” Obama said of the misconduct. “I will not tolerate this kind of behavior ... given the power that [the IRS] has and the reach that it has in all of our lives.” Obama also said he’d cooperate with Congress during its oversight review.
