Congress faces a potential government shutdown over immigration enforcement funding disputes following a controversial shooting by federal agents in Minnesota.

The U.S. government faces a partial shutdown starting at 12:01 a.m. Saturday over a $1.2 trillion spending package as Democrats demand removal of DHS funding after the Saturday killing of 37-year-old Alex Pretti by federal agents in Minnesota, while Republicans led by Senate Majority Leader John Thune want to pass the six-bill package unchanged.
