This InfoPAK is designed to help a company understand three areas of US law that regulate efforts to influence government decision-making: campaign finance law, lobbying disclosure law, and gift law. In this day and age, a successful company often needs to: (1) participate in selecting those who control government; (2) know what disclosure consequences arise from lobbying government; and (3) avoid nasty pitfalls relating to developing friendships in the government sector.
