Minnesota governor Tim Walz and Minneapolis mayor Jacob Frey among officials who received subpoenas

The justice department subpoenaed several top officials in Minnesota on Tuesday as part of its investigation into whether Minneapolis officials have conspired to impede federal immigration efforts there.

A copy of a subpoena to the office of the Minneapolis mayor, Jacob Frey, obtained by the Guardian, requests guidance and policies related to immigration enforcement in Minnesota since last year. It also requests communication regarding those policies with other state agencies, as well as documents related to “hindering, doxxing, identifying, or surveilling immigration officers”.
