Rep. Peter Visclosky, whose office has been subpoenaed for documents related to clients of the defunct lobbying firm PMA Group, has temporarily stepped down as chair of the House Energy & Water Appropriations Subcommittee. Lindsay Renick Mayer reports on Visclosky's woes, his top donors, and those of his replacement, Ed Pastor, who has taken less than a tenth as much in contributions from PMA Group and its clients (of course, I'm referring to contributions from their employees, family members and political action committees).
