A federal judge in Louisiana is set to rule today on whether the Trump administration has grounds to deport Mahmoud Khalil, a permanent U.S. resident and Columbia University graduate who helped organize campus protests against Israel’s assault on Gaza. Ahead of today’s ruling, Secretary of State Marco Rubio filed a brief, two-page memo conceding that Khalil has no criminal history and that the U.S. is seeking to deport him based purely on his beliefs.
