Indiana’s senior U.S. Senator Joe Donnelly will hold a town hall meeting in Ball State’s Emens Auditorium on Sunday.  The South Bend-area Democrat says he wants to answer questions from his constituents, and update the gathering on his work in Washington.  The town hall will begin at 1:30 p.m.  Doors will open at 12:30. The event is free and open to the public.  Donnelly will most likely run for re-election in 2018.
