MUSCATINE — The Muscatine City Council is considering whether to seek the removal of the city’s mayor. The council will meet Thursday night and vote whether to instruct the city attorney to file charges to remove Mayor Diana Broderson. Officials aren’t specifying the ground for removing the mayor, and council members declined to explain the matter. Broderson says she doesn’t understand the council’s actions but noted she’s received calls of support that included the proposal to remove the mayor.
