When Congress initiated an investigation into hydraulic fracturing that involved a PRG client, the PRG team was called upon to assist in clarifying and responding to the inquiry. Central elements of the team’s response included negotiating the rules of engagement with Congressional staff; preparing staff briefings in lieu of written responses when possible; and producing or protecting requested information. In addition to establishing a rapport with the majority staff who had initiated the request, PRG worked closely with the minority staff and other key committee members. The PRG team was ready when the committee issued a written report highlighting its findings, adeptly handling strategic communications and media relations. Based on this experience, and many others in the Congressional investigations context, the PRG team has developed a strong template of strategies to narrow the scope and limit the potential risks of investigations while maintaining good working relations with key Congressional staff.
