The case of Mahmoud Khalil, the Columbia University graduate student abducted by the Trump administration without a warrant and without any charges of a crime, is chilling. Khalil is a permanent legal resident, married to an American-born woman who is now 8 months pregnant and wondering if her husband will be home for the child’s birth. MSNBC’s Ayman Mohyeldin shows the painful footage of Khalil being detained and discusses why this will be a momentous case for the future of the First Amendment.
