This seminar explores the range of issues involved in congressional investigations, with special attention paid to the differing perspectives of the major players, both inside and outside of Congress, in a congressional investigation. Congressional investigations involve a unique interplay of legal and political issues. Legal issues -- involving such matters as the rights of private institutions and private citizens who may be implicated in a congressional investigation, the legal and political ability of the Executive Branch to resist congressional probes, the authority of the Judicial Branch to interfere with or limit the conduct of congressional investigations, and the relationship of congressional investigations to related criminal and civil inquiries conducted by other governmental entities -- must be factored into the political calculus of the contending political forces involved in a congressional investigation. Political determinations -- which underpin such issues as the scope and duration of an investigation or whether witnesses should be interviewed, deposed or called to testify live at a hearing -- may have significant legal ramifications. This seminar will address these issues at both the practical and the theoretical levels. As part of the course, class members will be asked to participate in mock problems concerning different aspects of the process.
