Minnesota launches investigation that could bring charges against federal immigration officers

A Minnesota prosecutor announced an investigation Monday that may lead to charges against federal officers, including Border Patrol official Greg Bovino, for misconduct during an immigration enforcement crackdown.

Hennepin County Attorney Mary Moriarty said in a news conference that her office is already looking into 17 cases, including one where Bovino threw a smoke canister at protesters on Jan. 21. Another on Jan. 7 involved federal officers making an arrest outside a high school and deploying chemical irritants while students and staff were in the area.

"Make no mistake, we are not afraid of the legal fight, and we are committed to doing this correctly," Moriarty said. "Operation Metro Surge caused immeasurable harm to our community."

The Department of Homeland Security, which oversees immigration enforcement, responded in a statement Monday night that such enforcement is a federal responsibility and states cannot prosecute federal officers.
