Trump Administration Fires All 22 Members of National Science Board in Sudden Purge

On Friday, April 24, 2026, the Trump administration terminated all 22 members of the National Science Board (NSB), the independent advisory body overseeing the U.S. National Science Foundation (NSF). The dismissals were communicated via a terse email sent to board members, stating, “On behalf of President Donald J. Trump, I’m writing to inform you that your position as a member of the National Science Board is terminated, effective immediately.” The administration provided no explanation for the decision, which scientists and policymakers have described as unprecedented and damaging to American scientific leadership.

An Unprecedented Move

The NSB, established by Congress in 1950, serves as the governing body for the NSF, advising both the president and Congress on national science and engineering policy. Its members, appointed by the president, serve staggered six-year terms to ensure continuity. The abrupt dismissal of the entire board disrupts this structure, leaving the NSF without its primary advisory body at a critical time for U.S. Research and innovation.

Dan Reed, a computer scientist at the University of Utah and former NSB chair (2022–2024), called the move “unprecedented.” In a statement to Nature, Reed emphasized the need for an “independent NSB, one representative of the broad science and engineering enterprise.” The lack of transparency surrounding the terminations has fueled concerns about political interference in federal science policy.

Impact on U.S. Science and Technology

The NSF is a cornerstone of U.S. Scientific research, funding fundamental studies across disciplines, from artificial intelligence to climate science. The NSB plays a key role in shaping the agency’s priorities, ensuring that investments align with national needs. With the board now dissolved, experts warn of potential disruptions to long-term research initiatives and talent development.

Keivan Stassun, a professor of physics and astronomy at Vanderbilt University and a terminated NSB member, described the dismissals as “a wholesale evisceration of American leadership in science and technology globally.” The move comes as the NSF director position has remained vacant for over a year, further destabilizing the agency’s leadership.

Scientists fear the administration may shift the NSF’s focus toward narrow priorities, such as artificial intelligence, at the expense of broader scientific inquiry. The NSB was scheduled to release a report in early May on how the U.S. Is losing ground to China in scientific research—a concern that may now go unaddressed.

Political Reactions and Historical Context

The dismissals have drawn sharp criticism from Democratic lawmakers. Rep. Zoe Lofgren (D-Calif.), ranking member of the House Committee on Science, Space, and Technology, condemned the move as “the latest stupid move made by a president who continues to harm science and American innovation.” She added, “It unfortunately is no surprise a president who has attacked NSF from day one would seek to destroy the board that helps guide the Foundation.”

Here’s not the first time the Trump administration has removed federal science advisers en masse. Previous actions included the dismissal of climate scientists from advisory panels and the elimination of the President’s Council of Advisors on Science and Technology (PCAST) in 2017. However, the termination of an entire governing board is unprecedented in the NSF’s 76-year history.

The NSF was created in 1950 with a mandate to “promote the progress of science” and maintain U.S. Leadership in research. President Harry Truman, in signing the legislation, stated, “We have come to know that our ability to survive and grow as a Nation depends to a very large degree upon our scientific progress. It’s not enough simply to keep abreast of the rest of the world in scientific matters. We must maintain our leadership.” The current dismissals raise questions about whether that leadership can be sustained.

What Comes Next?

The White House has not indicated whether it plans to appoint new NSB members or when the board might be reconstituted. Without a functioning advisory body, the NSF’s ability to set long-term priorities and respond to emerging challenges could be severely limited.

For now, the scientific community is left grappling with the implications of the dismissals. As one terminated board member told the Los Angeles Times, the move sends a troubling signal about the administration’s commitment to evidence-based policymaking. With global competitors like China investing heavily in research and development, the stakes for U.S. Science have rarely been higher.
