Two men who represented Indiana in the U.S. Senate for a combined 28 years, along with serving the state and nation in other key roles, will spend their retirements at Indiana University preparing the next generation of public servants. IU officials announced Wednesday former U.S. Sen. Evan Bayh, D-Ind., and former U.S. Sen. Dan Coats, R-Ind., each have been named distinguished scholars and appointed to posts in the Paul O'Neill School of Public and Environmental Affairs (Bayh) and the Hamilton Lugar School of Global and International Studies (Coats). Neither former lawmaker currently is scheduled to teach full time at the IU campus in Bloomington.
