Explanation:
In politics, lobbying, persuasion, or interest representation is the act of lawfully attempting to influence the actions, policies, or decisions of government officials, most often legislators or members of regulatory agencies. Lobbying, which usually involves direct, face-to-face contact, is done by many types of people, associations and organized groups, including individuals in the private sector, corporations, fellow legislators or government officials, or advocacy groups (interest groups). Lobbyists may be among a legislator's constituencies, meaning a voter or bloc of voters within their electoral district; they may engage in lobbying as a business. Professional lobbyists are people whose business is trying to influence legislation, regulation, or other government decisions, actions, or policies on behalf of a group or individual who hires them. Individuals and nonprofit organizations can also lobby as an act of volunteering or as a small part of their normal job. Governments often define and regulate organized group lobbying that has become influential.
