The "Intelligence Community Efficiency and Effectiveness Act of 2025" aims to comprehensively reform and streamline the Office of the Director of National Intelligence (ODNI) and the broader intelligence community. It modifies the Director of National Intelligence's (DNI) responsibilities by repealing authorities related to establishing new centers and transferring personnel, while shifting the DNI's role in oversight from "conduct" to "direct" independent reviews. The bill also mandates a plan to reform intelligence community acquisition processes, prioritizing commercial solutions to enhance efficiency.

The ODNI itself undergoes significant restructuring, with certain positions removed from its composition and its staff size capped at 650 full-time equivalent employees, excluding temporary task force members. The Principal Deputy Director of National Intelligence is redesignated as the Deputy Director, and other Deputy DNI roles are eliminated in favor of two new Assistant Directors for Mission Integration and Policy & Capabilities. These changes are intended to focus the ODNI on its core intelligence mission and reduce its overall footprint.

Several national intelligence centers are subject to major reorganization under this bill. The National Counterintelligence and Security Center (NCSC), including its staff and resources, is transferred to the Counterintelligence Division of the Federal Bureau of Investigation (FBI), with its director's duties shifting to the FBI's Assistant Director for Counterintelligence. This move aims to centralize counterintelligence functions within the FBI. The National Counterterrorism Center (NCTC) is reformed and redesignated as the National Counterterrorism and Counternarcotics Center, expanding its mandate to include counternarcotics. Its primary missions are narrowed, with strategic operational planning for counterterrorism transferred to the National Security Council, and its domestic intelligence activities are strictly limited to international terrorism.

The National Counterproliferation and Biosecurity Center (NCPBC) is transferred to the Central Intelligence Agency (CIA), its director's position terminated, and its duties absorbed by the CIA Director. The center is also renamed the National Counterproliferation Center, reflecting a reduction in its scope by removing biosecurity from its core focus. Additionally, the bill authorizes the DNI to convene temporary National Intelligence Task Forces composed of intelligence community employees to address specific intelligence priorities, providing a flexible mechanism for focused efforts that are time-limited and distinct from permanent ODNI staff.

Furthermore, the legislation mandates the termination of numerous existing positions, units, centers, councils, and programs across the intelligence community. These include the Intelligence Community Chief Data Officer, the Intelligence Community Innovation Unit, the Foreign Malign Influence Center, the Climate Security Advisory Council, the Office of Engagement, the Foreign Languages Program, and the Joint Intelligence Community Council. These repeals aim to eliminate what the bill deems redundant or inefficient structures within the intelligence apparatus.

Significant funding limitations are introduced, prohibiting the use of National Intelligence Program (NIP) funds for analytic collaboration with research or advocacy groups (think tanks) that receive foreign government support, except from Five Eyes intelligence-sharing allies. This measure seeks to prevent foreign influence on intelligence analysis. The bill also restricts the use of NIP funds for ODNI facilities deemed unnecessary by the Office of Management and Budget, requiring their sale or divestment, and mandates the termination of the National Intelligence University, requiring its complete wind-down.

Finally, a major provision explicitly prohibits the obligation or expenditure of NIP funds for any diversity, equity, or inclusion (DEI) practice within the intelligence community. It defines such practices broadly to include discrimination or mandatory training/assent to concepts of inherent superiority/inferiority based on race, sex, or other protected characteristics. The bill mandates the revision and rescission of all intelligence community regulations, policies, and training related to DEI practices to ensure compliance with this prohibition.
