A Minnesota prosecutor on Monday said her office is investigating the "potentially unlawful behavior" of federal agents during a crackdown earlier this year on undocumented immigrants that met widespread resistance and in which agents shot and killed two U.S. citizens, sparking nationwide outrage. Hennepin County Attorney Mary Moriarty, whose jurisdiction includes Minneapolis, said at a press conference that her office had created a portal that would allow the public to send in videos and other evidence of incidents they witnessed in which they think Gregory Bovino, who once called himself the "commander at large" of the U.S. Border Patrol, and other federal agents committed a crime.
