A US judge denied a bid by President Donald Trump's administration to dismiss detained Columbia University student Mahmoud Khalil's challenge to the legality of his arrest by immigration agents over his participation in pro-Palestinian protests, but moved the case to New Jersey. Manhattan-based US District Judge Jesse Furman agreed with the Justice Department that he did not have jurisdiction over the case. Khalil's lawyers have argued that his arrest violated free speech protections under the US Constitution's First Amendment. The case has become a flashpoint for the Republican president's pledge to deport non-US citizens who took part in protests against Israel's military campaign in Gaza.
