Columbia agreed to implement a mask ban, give campus security the power of arrest and apply oversight of Middle Eastern studies.

Update, March 21: Columbia University claims its mask ban allows for “medical exemptions”; it remains unclear whether such exemptions include people with existing health issues or who currently have an infectious disease, as with North Carolina’s statewide mask ban.

Columbia University has announced a new mask ban, the hiring of special officers and other new policies in response to the Trump administration's list of demands.
