In United States politics, the "iron triangle" comprises the policy-making relationship among the congressional committees, the bureaucracy, and interest groups,[2] as described in 1981 by Gordon Adams.
"[5] Central to the concept of an iron triangle is the assumption that bureaucratic agencies, as political entities, seek to create and consolidate their own power base.
This is accomplished by identifying potential allies that could significantly enhance its power in the political sphere, utilizing their civic intelligence to leverage collective social capital.
[12] Notably, within the more junior tiers of the bureaucracy, the intended recipients of an agency's services may not possess significant influence, resulting in their perception as ineffective supporters.
[22] On January 27, 2011, FBI Director Robert Mueller used "iron triangles" to refer to "organized criminals, corrupt government officials, and business leaders" which he said "pose a significant national security threat".
