The Portland Police Bureau released the following statement today:
On June 16, 2021, Portland Police Bureau employees serving as members of the Rapid Response Team (RRT) left their voluntary positions and no longer comprise a team. Its members were sworn employees of the Portland Police who served on RRT in addition to their daily assignment in the Bureau. Despite no longer serving on RRT, they will continue in their regular assignments. There were approximately 50 employees serving as RRT members.
The Rapid Response Team is an all-hazard incident response team that has received advanced specialized training to respond to incidents requiring higher levels of technical expertise including public order policing, natural or man-made disasters. The primary role has been to provide public safety at crowd events when there was a threat of harm to the community. All Rapid Response Team members are trained in advanced skills related to crowd management and crowd control including crowd psychology and behavior, team formations and movements, the use of enhanced personal protective equipment, use of force, de-escalation and arrests.

The Post Millennial reported: 
The Rapid Response Team, a unit within the Portland police department, voted unanimously to resign on Wednesday during a meeting with the police union. This follows the criminal indictment of an officer for assault stemming from a riot in August 2020, sources within the police bureau told The Post Millennial.
Officer Corey Budworth was on the Rapid Response Team, a group police officers that volunteer for the post, and are deployed to respond to riots, civil unrest, and demonstrations in Portland. Budworth was indicted and charged with one count of fourth degree assault, a misdemeanor by Multnomah District Attorney Mike Schmidt’s office on Tuesday.
On the night of August 18, 2020, Antifa militants threw a Molotov cocktail into the County Sheriff’s Department Headquarters as the Rapid Response Team struggled to contain the riot. In a statement  released after the indictment, Schmidt said “In this case, we allege that no legal justification existed for Officer Budworth’s deployment of force, and that the deployment of force was legally excessive under the circumstances.
Good for them. Why put yourself in extra danger for the public, politicians, and an administration that doesn’t support you?
