Answer:
An organization that pressures elected officials to enact legislation favorable to its causes.
Explanation:
The most common type of interest group is formed around businesses, corporations, and trade associations. Part of their reputation for power is based on the fact that they represent about half of all interest groups in Washington. People who criticize interest groups for having undue power in government believe that the business groups get special privileges for people who already have more wealth and power than ordinary citizens. For example, the oil and tobacco industries each have interest groups who promote their respective interests on Capitol hill.
