Another outside, multi-billion-dollar corporation, this time in Switzerland, is trying to come into northern Minnesota and create a copper-nickel (sulfide) mine.

She spent a majority of the show talking about the Polymet mining project that is being proposed upstream of the St. Louis River, which drains into Lake Superior. She also made arguments recently fighting the project to the Minnesota Supreme Court.
