House Ways and Means Committee Chairman Rep. Dave Camp , R-Mich., and Rep. Sander Levin, D-Mich., right, the ranking member, exchange words during a disagreement over procedure as the panel debates whether IRS official Lois Lerner’s refusal to testify to Congress deserves criminal prosecution, on Capitol Hill in Washington, Wednesday, April 9, 2014. After Rep. Levin’s insistence that he, the top Democrat, be heard, Chairman Camp told Levin to “chill out.” Levin replied that he was “very chilled out.” Ways and Means wants the Justice Department to open a criminal probe against Lerner.
