President Trump dissolved the President's Council of Advisors on Science and Technology through Executive Order 14177, signed on January 23, 2025. The action terminated a longstanding institutional mechanism that had provided scientific and technological guidance to the executive branch across multiple administrations. The council previously served as a formal advisory body through which the nation's leading scientists and technologists could directly counsel the president on policy matters spanning climate, health, technology, and national competitiveness. The executive order eliminated the council's operations entirely, severing this advisory function from the executive branch structure.

The dissolution directly affects the scientific community's institutional access to executive decision-making. Research scientists, technology leaders, and academic institutions that had previously participated in or benefited from PCAST's policy recommendations lose a formal channel for scientific input into federal governance. The action also impacts federal agencies that historically relied on PCAST recommendations when developing science and technology policy initiatives. Career scientists within government who worked with the council to translate research into policy guidance face diminished influence over executive decisions.

This action compounds a broader pattern of reducing scientific authority within the Trump administration. The same day the president signed the dissolution order, his administration terminated National Science Board members, removing scientists from governance roles at the National Science Foundation. Months earlier, the administration had prevented CDC publication of peer-reviewed vaccine efficacy research, limiting public access to scientific findings. These actions collectively narrow the institutional pathways through which scientific expertise reaches policy makers. While the administration simultaneously issued Executive Orders on artificial intelligence development and biological research safety, those orders reflect regulatory priorities rather than scientific advisory input, suggesting policy decisions are being made through executive directives rather than structured scientific counsel.

No court challenges to the dissolution have been reported, though the action represents a significant reduction in the formal science advisory infrastructure available to future administrations. A reversal would require either a new executive order restoring the council or congressional action to statutorily establish similar advisory mechanisms.
