Jack Allan Abramoff is an American lobbyist, businessman, film producer, writer, and convicted felon. He was at the center of an extensive corruption investigation led by Earl Devaney that resulted in his conviction and 21 other people either pleading guilty or being found guilty, including White House officials J. Steven Griles and David Safavian, U.S. Representative Bob Ney, and nine other lobbyists and congressional aides.

Lobbying in the United States describes paid activity in which special interest groups hire well-connected professional advocates, often lawyers, to argue for specific legislation in decision-making bodies such as the United States Congress. It is often perceived negatively by journalists and the American public; critics consider it to be a form of bribery, influence peddling, and/or extortion. Lobbying is subject to complex rules which, if not followed, can lead to penalties including jail. Lobbying has been interpreted by court rulings as free speech protected by the First Amendment to the U.S. Constitution. Since the 1970s, the numbers of lobbyists and the size of lobbying budgets has grown and become the focus of criticism of American governance.
