Rep. Pat Tiberi, R-Ohio, right, joined by Rep. Dave Reichert, R-Wash., left, questions Internal Revenue Service Commissioner John Koskinen as he faces the House Ways and Means Committee in their continuing probe of whether tea party groups were improperly targeted for increased scrutiny by the IRS, on Capitol Hill in Washington, Friday, June 20, 2014. The IRS asserts it can't produce emails from seven officials connected to the tea party investigation because of computer crashes, including the emails from Lois Lerner, the former IRS official at the center of the investigation who has invoked her Fifth Amendment right at least nine times to avoid answering lawmakers' questions.
