Gov. Tim Walz (D-MN) has called for an investigation into outgoing Homeland Security Secretary Kristi Noem following bipartisan criticism over the department’s issuance of an exorbitant, no-bid contract and immigration enforcement practices in Minnesota.

Walz turned the tables on Noem Tuesday, following months of criticism from Republicans over his state’s $9 billion worth of fraud in social services and Medicaid programs.
