Attorney General Ellen Rosenblum today removed Darin Tweedt, the chief of the Oregon Department of Justice's criminal division, from his post.

"After more than three years in office, the Attorney General felt like this was the right time to make a leadership change within her Criminal Justice Division," Rosenblum's spokeswoman Kristina Edmunson tells WW in a statement.

Tweedt's group has been under scrutiny in recent months because one of the investigators in the criminal justice section used a computer surveillance tool called "Digital Stakeout" to monitor people using hashtags like "Black Lives Matter" and "Fuck the Police" on Twitter.

Among the people the agent apparently monitored for using the hashtag: one of the agency's lawyers, civil-rights division chief Erious Johnson.

When Rosenblum did not take immediate action in October, the Urban League of Portland, whose executive director Nkenge Harmon Johnson is married to Erious Johnson, demanded an investigation.

In November, Rosenblum hired a lawyer from the Stoel Rives firm to find out what happened. That investigation is ongoing. (Disclosure: Rosenblum is married to Richard Meeker, the co-owner of WW's parent company.)

Rosenblum's top deputy, Fred Boss, announced to all DOJ staff via email this afternoon that Rosenblum was removing Tweedt from his position and reassigning him within the agency.

Here's that announcement:

I wanted to alert you to a leadership change within the Criminal Justice Division. Darin Tweedt will no longer serve as Chief Counsel of the Criminal Justice Division. During this transition, Michael Slauson, the Attorney General’s Special Counsel on Public Safety, will serve as the acting division administrator until a permanent Chief Counsel is appointed.

Darin will continue to work as a Senior Assistant Attorney General within the Department of Justice, and I would like to especially thank him for his service as Chief Counsel for 5 years and for his ongoing commitment to DOJ.

Michael Slauson previously worked in our Criminal Justice Division from September 2002 to July 2013, and has subsequently served in multiple roles throughout the agency, including most recently as a key advisor to the Attorney General. Michael has years of experience prosecuting complex cases and upholding criminal convictions, and I know he will use his open communication style and strong ties within the criminal justice community to provide immediate support to the division.
