Palestinian activist Mahmoud Khalil appeals to SCOTUS to halt deportation

What This is

• Mahmoud Khalil has asked the U.S. Supreme Court for emergency help to stop immigration authorities from re-arresting and deporting him while his case continues.
• Khalil is a Columbia graduate and lawful permanent resident who was arrested in 2025 amid pro-Palestinian campus protests.
• A divided federal appeals court said his challenge should proceed through the immigration system first, rather than through a federal district court case right now.
• The appeal centers on whether federal immigration law blocks federal judges from ordering someone’s release from immigration detention while deportation proceedings are still pending.
• His lawyers want the Supreme Court to clarify whether noncitizens can sue in federal court when they claim immigration officials punished them for protected speech.
• Khalil says the government targeted him for deportation and detained him in retaliation for pro-Palestinian speech that he argues is protected by the First Amendment.

Why This Matters

• The outcome could decide how quickly noncitizens can get a federal judge to hear constitutional claims, rather than waiting for immigration proceedings to finish.
• The case presses a core free-speech issue: whether immigration enforcement can be used to punish or chill political activism.
• It could shift power in practice between immigration agencies that detain people and judges who can order release while cases are pending.
