JENA, La. (AP) 鈥 Detained Columbia University student activist Mahmoud Khalil appeared briefly Friday in immigration court at a remote Louisiana detention center as his lawyers fight in multiple venues to try to free him.

Khalil, 30, a legal U.S. resident with no criminal record, sat alone next to an empty chair through a brief court session that dealt only with scheduling. His lawyer participated via video.

Khalil swayed back and forth in his chair as he waited for the proceeding to begin in a windowless courtroom inside an isolated, low-slung Immigration and Customs Enforcement detention complex. Ringed by two rows of tall barbed-wire fences and surrounded by pine forests, the facility is near the small town of Jena, roughly 150 miles (240 kilometers) north of Louisiana's capital, Baton Rouge.

Khalil smiled at two observers as they came into the room, where just 13 people ultimately gathered, including the judge, attorneys and court staff. Two journalists and a total of four other observers attended.

By video, lawyer Marc Van Der Hout said he'd just started representing Khalil and needed more time to speak to him, get records and delve into the case. An immigration judge set a fuller hearing for April 8.

Khalil's lawyers also to challenge his detention and potential deportation, which looms as his wife, a U.S. citizen, is expecting their first child. A federal judge in New York ruled Wednesday that Khalil but that the case should be moved to a New Jersey federal court.

The Columbia University graduate student was on March 8 as part of President Donald Trump鈥檚 crackdown on what he calls antisemitic and 鈥渁nti-American鈥 campus protests. Khalil last year for pro-Palestinian demonstrators who opposed Israel鈥檚 military campaign in Gaza.

Protesters, some of them Jewish, say it's not antisemitic or anti-American to criticize Israeli military actions and advocate for Palestinian human rights and territorial claims.

However, some Jewish students have said the demonstrations didn't just criticize Israel's government but launched into rhetoric and behavior that made Jews feel unwelcome or outright unsafe on the Ivy League campus. A Columbia task force on antisemitism found 鈥渟erious and pervasive鈥 problems at the university.

White House press secretary Karoline Leavitt has asserted that Khalil organized disruptive protests that harassed Jewish students and "distributed pro-Hamas propaganda.鈥 Hamas, the militant group that controls Gaza and attacked Israel in October 2023, is designated by the U.S. as a terrorist organization.

The U.S. government is seeking to deport Khalil under a rarely used statute that allows for removing noncitizens who pose 鈥減otentially serious adverse foreign policy consequences for the United States.鈥

Khalil, an Algerian citizen who was born in Syria to a Palestinian family, in a statement that his detention reflects 鈥渁nti-Palestinian racism鈥 in the U.S. Before his detention by the government, he said that a Columbia disciplinary investigation him for being an identifiable figure at the protests.

Columbia now is contending with broader pressure to address the Trump administration's assertions of antisemitism, including unprecedented at the private university if it wants to continue receiving federal grants for research and other purposes.

The private university announced Friday that it was concerning protests, disciplinary procedures, the Middle Eastern studies department and other matters.
