Example of Iron Triangle

The iron triangle is an expression coined by political scientists to describe the relationship between Congress, the bureaucracy and interest groups. This relationship relates to the direct feeds between these groups, and their influence on each other:

Interest groups support Congress members.
Congress members promote the cause of interest groups.
The bureaucracy provides policy options.

This means that any action by one party naturally affects the other two.

Examples of Iron Triangle:

An interest group lobbies Congress members to make legislation in their favor.
Congress refers the matter to the bureaucracy for policy evaluation and options.
The bureaucracy provides the policy evaluation, and prepares legislation based on the decision of the Congress members.
