Border Patrol Chief Gregory Bovino posted a video message in support of federal immigration officers after he and some of his agents left Minneapolis in the wake of a lethal shooting. President Donald Trump sent border czar Tom Homan to Minnesota to address growing rioting and protests after Alex Pretti was shot and killed by federal officers Saturday. 'I’ve got your back, now and always — I love you, I support you, and I salute you.' Bovino, who has been lauded for his "turn and burn" tactics by immigration hawks, issued a statement of love and support for his officers in the social media video. Both Frey and Walz have said their goal is to shut down all federal immigration enforcement in Minnesota.
