In Chicago, a COVID-19 unit nurse said she resigned Monday after hospital administrators barred her from wearing an N95 protective mask she brought with her to work. The nurse, Imarís Vera, posted this video on social media.

Imarís Vera: “I had my own N95 mask. I told my manager, 'I understand we're short on supplies, but let me protect myself. Let me feel safe. I have family that I have to come home to.’ And the way things are looking, this isn’t going to get any better. America is not prepared, and nurses are not being protected.”

In Austin, Texas, 28 young adults tested positive after a spring break trip to southern Baja California in Mexico, with dozens more under public health investigation. Meanwhile, Russia has promised to deliver a planeload of personal protective equipment and other medical supplies after President Trump placed a call to Vladimir Putin Monday.
