Nurses honor fellow nurse Alex Pretti's life and service

"We all say an oath when we graduate from nursing school, and he upheld that oath until the very end."

Nurses at Alex Pretti's memorial in Minneapolis spoke to our reporters Nate Halverson and Sam Van Pykeren on Monday about gathering to honor a fellow nurse, who they say helped others until the very end.

Pretti, a US citizen and Minneapolis local, worked in the intensive care unit at a Veterans Affairs hospital. Videos detail the last moments leading up to his death: He was directing traffic on the street while filming immigration agents, attempted to assist another observer who was pushed to the ground by immigration enforcement, pepper-sprayed by the agent who ends up shooting him, and tackled by several agents onto the street.

"That's what nurses do," labor and delivery nurse Sarah Evans said. "We care and protect. So we'll do what we can to be in between harm and another person."
