President Donald Trump signed an executive order Thursday requiring U.S. colleges to protect free speech on their campuses or risk losing federal research funding. The new order directs federal agencies to ensure that any college or university receiving research grants agrees to promote free inquiry and to follow federal rules and regulations supporting free speech. “Even as universities have received billions and billions of dollars from taxpayers, many have become increasingly hostile to free speech and to the First Amendment,” Trump said at a White House signing ceremony.
