All 22 members of the National Science Board were terminated by the Trump administration via a terse email on Friday.

The administration has provided no explanation for purging the board, which helps steer the National Science Foundation and acts as an independent advisory body for the president and Congress on scientific and engineering issues, providing reports throughout the year. The ousters represent another severe blow to the NSF and the overall scientific enterprise in America.

Members received a two-sentence email saying that, “On behalf of President Donald J. Trump,” their positions were “terminated, effective immediately.”

Keivan Stassun, a professor of physics and astronomy at Vanderbilt University and director of the Vanderbilt Initiative in Data-intensive Astrophysics, was among those terminated. After reaching out to fellow board members and finding that they, too, had been terminated, he described the move to The Los Angeles Times as “a wholesale evisceration of American leadership in science and technology globally.”

NSB members are appointed by the president and serve six-year terms, which overlap to provide continuity. Other members who spoke to reporters at Nature News told the outlet that the board was set to meet on May 5 and planned to release a report on how the US is ceding ground to China on scientific endeavors.

Assault on science

The NSF and the board were established by President Harry Truman in 1950. “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,” Truman said after creating them. “Moreover, it is not enough simply to keep abreast of the rest of the world in scientific matters. We must maintain our leadership.”
