NEW YORK (AP) — Three months after his release from an immigration jail, Palestinian activist Mahmoud Khalil is facing the growing threat of deportation for his role in campus protests against Israel.

In court documents made public Wednesday, an immigration judge in Louisiana ruled that Khalil should be deported for failing to disclose information on his green card application.

The decision marked a setback for Khalil, a lawful U.S. resident and recent Columbia University graduate student who became the first person targeted by President Donald Trump’s aggressive crackdown on pro-Palestinian activists. But while the ruling puts him one step closer to a final order of removal, it is far from the last word in the case.

For now, Khalil remains protected from detention and deportation under a separate judicial order. His legal team has said they intend to appeal the immigration judge’s ruling, which Khalil has characterized as “further evidence of retaliation” from a “kangaroo court.”
