CBS News first reported the investigation. https://www.pbs.org/newshour/politics/justice-department-investigates-minnesota-gov-walz-and-minneapolis-mayor-frey

In response to reports of the investigation, Walz said in a statement: "Two days ago it was Elissa Slotkin. Last week it was Jerome Powell. Before that, Mark Kelly. Weaponizing the justice system and threatening political opponents is a dangerous, authoritarian tactic."

Walz's office said it has not received any notice of an investigation.

"This is an obvious attempt to intimidate me for standing up for Minneapolis, our local law enforcement, and our residents against the chaos and danger this Administration has brought to our streets," Frey said in a statement. "I will not be intimidated. My focus will remain where it's always been: keeping our city safe.

The investigation comes during a weekslong immigration crackdown in Minneapolis and St. Paul that the Department of Homeland Security has called its largest enforcement operation, resulting in more than 2,500 arrests.

The operation has become more confrontational since the fatal shooting of Renee Good on Jan. 7. State and local officials have repeatedly told protesters to remain peaceful.
