The announcement this week that Cornerstone Chamber of Commerce is moving from Benton Harbor to St. Joseph doesn’t faze Benton Harbor Mayor Marcus Muhammad. He tells WSJM News he wishes the chamber luck. Cornerstone Alliance is remaining behind and moving to a bigger facility downtown, while the chamber is heading off to Ship Street in downtown St. Joe. Mayor Muhammad says he’s not disappointed to hear the chamber is moving, adding he recognizes each entity’s need to follow its best interests. He also says the city is willing to work with any and all organizations that pursue economic development. Muhammad says the doors are always open to those who want to move the city forward.
