A prosecutor who was co-counsel in the case against Kim Potter, the former Brooklyn Center police officer who is facing manslaughter charges for fatally shooting Daunte Wright, resigned on Monday (May 24).

Imran Ali, who served in the Washington County Attorney’s Office in Minnesota for 10 years, wrote a letter to his boss County Attorney Pete Orput announcing the resignation. “The last several weeks have been difficult for my family,” he wrote. “The vitriol from some and the infusion of partisan politics by many has made my job difficult to pursue justice. I pray that our state heals and the extreme partisan platforms dissipate. We must return to thoughtful discourse that unites, not impulsive, irrational talking points that divide. Until then, there will be no peace and no justice.”

The announcement comes just days after Minnesota Attorney General Keith Ellison announced that he would be leading the prosecution against Potter.

“Daunte Wright was a son, a brother, a father, a friend. I did not seek this prosecution and do not accept it lightly,” Ellison told CBS Minnesota. “I have had, and continue to have, confidence in how both County Attorney Orput and County Attorney Freeman have handled this case to date. I thank County Attorney Orput for the solid work he and his office have done, and I thank County Attorney Freeman once again for his confidence in my office.”

“Once again, we in Minnesota find ourselves at a moment where a deadly-force encounter with police has galvanized our grief and focused our attention,” Ellison added. “If prosecutors ensure that prosecutions are vigorous and swift, if legislators at every level pass long-overdue reforms, if police leadership demonstrates misconduct has no place in the profession, and if [the] community continues to keep up the cry for justice, we will break the cycle of history and establish a new standard for justice.”

Potter is currently facing a second-degree manslaughter charge for the deadly shooting. Ellison has not indicated whether or not he plans to upgrade the charge to murder. Last week, a judge set a tentative trial date for the former cop to begin on Dec. 6.
