A federal judge in the United States has ordered the release of Salah Sarsour, a Palestinian American Muslim leader and president of the Islamic Society of Milwaukee (the largest mosque in the Midwestern state of Wisconsin), who argued his detention by Immigration and Customs Enforcement (ICE) was retaliation for his pro-Palestinian advocacy. US District Judge James Patrick Hanlon ruled on Thursday that Sarsour had raised a substantial claim that he was targeted for speech protected under the First Amendment, and dismissed the Trump administration's argument that pro-Palestinian expression undermines US foreign policy interests, writing that "the mere invocation of foreign relations concerns does not automatically trump First Amendment rights." Sarsour, a legal permanent resident who has lived in the US for nearly 32 years, was released hours after the ruling and returned to Wisconsin, though his deportation case continues.
