Walmart, Target, and some businesses are not leaving the city at all. Nor is Frey pleading with Walmart and Target not to leave. That is fake news.
What is happening, and has been reported, is that 7-Sigma, a manufacturing company that has been located in Minneapolis for over thirty years is leaving. That is one. Are there others? Perhaps. Target and Walmart are not among them.
It is unlikely all businesses can simply just pick up and go. And Walmart and Target have only temporarily closed locations with plans to re-open.
