Democratic officials and protesters on the streets are demanding that federal immigration officers leave Minnesota after a Border Patrol agent fatally shot a man in Minneapolis. Saturday's shooting drew hundreds of demonstrators into the frigid cold in a city already shaken by another killing weeks earlier. Minneapolis Police Chief Brian O’Hara says information about what led up to the latest shooting is limited. The man has been identified by his parents as Alex Pretti. He was a 37-year-old intensive care unit nurse. The Minnesota National Guard assisted local police in monitoring the crowds.
