President Trump to Visit Indiana09/21/2017 President Donald Trump will visit Indiana next week. That according to a tweet from the Indiana Republican Party. But that’s all it said, no other details were given on the when or where. The visit comes as Trump is trying to persuade Democratic Indiana Sen. Joe Donnelly to support a GOP-led tax overhaul. Donnelly faces re-election next year and is considered one of the most vulnerable Senate Democrats after Trump easily won Indiana in last year's election.
