The Minnesota police officer who shot and killed Daunte Wright has resigned. The police chief also stepped down.

• The police officer who shot and killed Daunte Wright has resigned.
• Kimberly Potter announced her resignation in a letter to city officials Tuesday.
• Police Chief Tim Gannon has also resigned, city officials said.

Kimberly Potter, the Brooklyn Center, Minnesota, police officer who shot and killed 20-year-old Daunte Wright during a traffic stop on Sunday, has resigned. The city's police chief, Tim Gannon, also resigned following the deadly shooting.

The resignations were first reported by the Star Tribune.

"I am tendering my resignation from the Brooklyn Center Police Department effective immediately," Potter wrote in a letter addressed to Brooklyn Center Mayor Mike Elliott, Acting City Manager Reggie Edwards, and Gannon.

"I have loved every minute of being a police officer and serving this community to the best of my ability but I believe it is in the best interest of the community, the department, and my fellow officers if I resign immediately," she said.

Elliott said both officer Porter and chief Gannon sent their letters of resignation as of Tuesday morning.

Wright was killed after he was pulled over by police in the Minnesota suburb Sunday afternoon.

His mother said Wright called her after being pulled over and told he was stopped by police because of "air fresheners hanging from his rearview mirror." Police said he was pulled over because of an expired vehicle registration.

Police say Potter shot Wright as he attempted to flee. His car struck another vehicle, and he was pronounced dead at the scene. Gannon said Monday that Potter accidentally drew her gun instead of a Taser when apprehending Wright. Potter was a 26-year veteran of the police force.

His death has sparked protests and unrest. Activists and Elliott had called for Potter to be fired and face "full accountability."

"In any other line of work, if you kill someone… you are at the very least going to lose your job," Elliott said during an appearance on CBS "This Morning" earlier Tuesday. "And so my position has been that I do believe the officer should be fired. I do believe she should lose her job."

Potter had been placed on administrative leave pending an investigation.
