Governor Tim Walz says ‘weaponizing the justice system is an authoritarian tactic’ as he and Minneapolis mayor Jacob Frey reportedly will be subpoenaed

The US justice department is investigating Minnesota’s political leaders for allegedly conspiring to obstruct the Trump administration’s controversial immigration crackdown there, according to multiple reports.

The investigation, which CBS News first reported, marks an extraordinary use of federal power to challenge two of the crackdown’s most vocal Democratic critics, including the state’s governor, Tim Walz, and the mayor of Minneapolis, Jacob Frey.
