History of lobbying in the United States
The history of lobbying in the United States is a chronicle of the rise of paid advocacy generally by special interests seeking favor in lawmaking bodies such as the United States Congress. Lobbying has usually been understood as activity by paid professionals to try to influence key legislators and executives, which is different from the right for an individual to petition the government.
