Rep. Charles Boustany, R-La., chairman of the Ways and Means Oversight Subcommittee, drills Internal Revenue Service Commissioner John Koskinen as the full committee continues its probe of whether tea party groups were improperly targeted for increased scrutiny by the IRS, on Capitol Hill in Washington, Friday, June 20, 2014. Listening at left is Rep. Peter Roskam, R-Ill. 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.
