The Justice Department is investigating Governor Tim Walz and Mayor Jacob Frey over possible obstruction of federal law enforcement, according to a CNN report.

* Grand jury subpoenas have been issued, but neither office had received notice as of Friday evening; the Justice Department declined to comment.

* Walz said the probe is “weaponizing the justice system,” calling it a “dangerous, authoritarian tactic.”

* Frey said the investigation is an attempt to intimidate him and said he will not be intimidated.
