Former President Barack Obama urged universities to resist attacks from the federal government that violate their academic freedom in a campus speech on Thursday. He also called on schools and students to reflect on their speech environments. Obama's comments come as the Trump administration threatens universities with major cuts and suspensions of funding. Many universities are unsure of how to respond, but some presidents have vowed to fight back in defense of academic freedom. Obama also called on law firms to stand for their principles, even if it means risking business.
