Indiana’s three Republican U.S. Senate candidates – Reps. Luke Messer and Todd Rokita, and businessman Mike Braun – will meet Monday evening for the final debate before the May 8 primary.

That's amid controversy that’s swirled around the event hosted by the nonpartisan Indiana Debate Commission.

Last month, Rokita said no to the Indiana Debate Commission. Commission President Gerry Lanosga says he was surprised.
