All 12 members of the board overseeing the prestigious Fulbright scholarships on Wednesday resigned in protest of what they call the Trump administration’s meddling with the selection of award recipients, according to a statement.

A statement published online by the board members said the administration usurped the board’s authority by denying awards to “a substantial number of people” who already had been chosen. Another 1,200 award recipients who were already approved to come to the U.S. are undergoing an unauthorized review process that could lead to their rejection, the board members said.

“To continue to serve after the Administration has consistently ignored the Board’s request that they follow the law would risk legitimizing actions we believe are unlawful and damage the integrity of this storied program and America’s credibility abroad,” the statement reads.

Congress established the Fulbright program nearly 80 years ago to promote international exchange and American diplomacy. The highly selective program awards about 9,000 scholarships annually in the U.S. and in more than 160 other countries to students, scholars, and professionals in a range of fields.

A message seeking comment was left with the State Department, which runs the scholarship program.

The resignations were first reported by The New York Times.

The intervention from the Trump administration undermined the program’s merit-based selection process and its insulation from political influence, the board members wrote.

“We believe these actions not only contradict the statute but are antithetical to the Fulbright mission and the values, including free speech and academic freedom, that Congress specified in the statute,” the statement said. “It is our sincere hope that Congress, the courts, and future Fulbright Boards will prevent the administration’s efforts to degrade, dismantle, or even eliminate one of our nation’s most respected and valuable programs.”

Award recipients are selected in a yearlong process by nonpartisan staff at the State Department. The recipients who had their awards canceled are in fields including biology, engineering, medical sciences, and history, the board members said.

The announcement comes as the Trump administration ratchets up scrutiny of international students on several fronts. The administration has expanded the grounds for revoking foreign students’ legal status, and recently paused scheduling of new interviews for student visas as it increases vetting of their social media activity. The government also has moved to block foreign students from attending Harvard as it pressures the Ivy League school to adopt a series of reforms.
