In Minneapolis, state investigators tell 60 Minutes that the federal government is not sharing evidence regarding the killing of Alex Pretti by federal immigration agents. “The federal government appears to be shutting the state investigators out completely. And that's very unusual and, in fact, unprecedented, in my experience,” says Sam Trepel, a former Civil Rights Division prosecutor. Last week, the Trump administration responded to the criticism. The leader of the Minneapolis operation, Gregory Bovino, was replaced by Tom Homan, a top White House official on deportations who reports to the president. Homan met with the mayor of Minneapolis and the governor of Minnesota. 60 Minutes asked for interviews with Homeland Security Secretary Kristi Noem, Homan, and others, but none were made available. #minneapolis #alexpretti #federalinvestigation #uspolitics
