Book excerpt: Increasingly, former members of Congress are finding their way back into the corridors of power representing the very interest groups they once regulated. As lobbyists, former members of Congress carry significant clout that gives them access not only to their former colleagues in the House of Representatives and Senate, but also to members of the executive branch. This book evaluates why former members of Congress become lobbyists, and the implications of this career choice on pubic policy. Do Members of Congress Reward Their Future Employers? argues that post-congressional lobbying has the potential to undermine sound public policy and may ultimately jeopardize the legitimacy of the institution.
