Activist Appeals to Supreme Court Over Free Speech Rights

Mahmoud Khalil, a former Columbia graduate student and pro-Palestinian activist, has appealed to the U.S. Supreme Court, seeking to sue the Trump administration for allegedly violating his First Amendment rights. Khalil was arrested in March 2025 and held for over 100 days in U.S. Immigration and Customs Enforcement custody. His detention preceded a deportation attempt initiated after Secretary of State Marco Rubio made an unusual determination that Khalil's pro-Palestinian activities compromised a compelling U.S. foreign policy interest.

A divided federal appeals court had previously ruled that Khalil, who holds a green card and is married to an American citizen, could not litigate his claims until his immigration proceedings were complete.

Khalil contends he was targeted by the administration as part of a crackdown on pro-Palestinian protests and discussions surrounding Israel's war in Gaza. He has not been charged with any crime. Following a legal challenge, he was released from custody pending the outcome of his petition.

"This fight is not only about whether I get to stay in this country," Khalil stated during a remote press conference. "It’s about whether anyone in this country can speak out for Palestinians without being punished for it."

A White House spokeswoman commented that the executive branch has the authority to take actions to protect the country and its immigration system. The spokeswoman added, "Khalil obtained his visa by willfully and intentionally failing to accurately report information relevant to his background. Those who lie to the government to obtain entry into the United States will face justice."

The central legal question revolves around the writ of habeas corpus, a procedure allowing individuals detained by the government to challenge their confinement before a judge. If the Supreme Court agrees to hear the case, it would allow Khalil's allegations of retaliatory government action based on disfavored speech to proceed. A denial of the appeal could lead to his deportation without the opportunity to present his case in court.

Khalil's attorney, Baher Azmy, described the situation as an "unprecedented weaponization of immigration power," asserting that Khalil has committed no crime and his detention is solely due to speech the government disapproves of. The core issue, Azmy stated, is whether federal courts can address this action.

Khalil also has a separate legal challenge pending in the 5th Circuit Court of Appeals concerning U.S. immigration law. He emphasized that his situation is representative of broader issues faced by many immigrants.

The Supreme Court is expected to consider the petition in January. If the case is accepted, oral arguments would likely occur in the spring, with a decision anticipated by the end of June.
