The Trump administration moved early Friday to detain an international student at Cornell University who has led protests on its Ithaca, N.Y., campus, in what appeared to be the latest effort to kick pro-Palestinian activists out of the United States.

A lawyer for Momodou Taal, a doctoral student in Africana studies, said in court papers that he had been notified by email early Friday morning that U.S. Immigration and Customs Enforcement was seeking Mr. Taal’s surrender.

Last year, Mr. Taal was among a group of pro-Palestinian activists who shut down a career fair on the Cornell campus that featured weapons manufacturers. As a result, the university had ordered him to study remotely for the spring semester.

Mr. Taal, a great-grandson of Gambia’s first president, Sir Dawda Kairaba Jawara, is a citizen of both Gambia and the United Kingdom. According to court documents, Mr. Taal, who is here on a visa, said he feared deportation in part because his name had been circulated on social media and in media reports as a potential ICE target.

The move to detain Mr. Taal comes as the Trump administration tries to deport other pro-Palestinian students and academics.

About two weeks ago, Mahmoud Khalil, a permanent U.S. resident of Palestinian descent who recently obtained a master’s degree from Columbia University, was detained in New York. On Monday, the government detained Badar Kahn Suri, an Indian citizen who was studying and teaching at Georgetown University, claiming he had violated terms of his academic visa. Other students have also been targeted.

ICE did not immediately return a request for comment.

Last weekend, Mr. Taal filed a pre-emptive lawsuit to block possible action against him. A hearing had been scheduled in that case for Tuesday in Syracuse, N.Y. A lawyer for Mr. Taal, Eric T. Lee, argued in the lawsuit that his client was exercising his right to free speech and that there were no legitimate grounds for his deportation.

The lawsuit also challenged the legality of Mr. Trump’s executive order to “combat antisemitism” that instructed federal agencies to deport immigrants whose actions could be regarded as “antisemitic or supportive of terrorism.”

Earlier this week, neighbors saw law enforcement agents near Mr. Taal’s apartment building by Cornell’s campus, according to affidavits filed in the lawsuit in the Northern District of New York.

“This does not happen in a democracy. We are outraged, and every American should be too,” Mr. Lee said in a statement.

Lawyers for Mr. Taal are asking the court to delay his surrender to ICE, pending the outcome of the litigation. On Thursday, hundreds of Cornell students and supporters held a rally in support of Mr. Taal, who is also the host of a podcast called “The Malcolm Effect.”
