Portland Police Deputy Chief Bob Day wrote the email June 19, replying to a formal request for assistance from the Federal Protective Service, a police division within the Department of Homeland Security. "At this time I am denying your request for additional resources from PPB," Day wrote. "I recognize this is a fluid situation that will need continuous monitoring. I am willing to revisit this inquiry after you have exhausted all alternative options besides arrests and maximized the use of FPS resources. We will respond to [calls] for assistance if your officers are assaulted and need us to facilitate a safe exit from the conflict."
