Scott Walker announced Thursday.Haribo of Bonn, Germany, will invest $242 million in the plant and create 400 jobs there when the factory opens in 2020, Walker said.“These are well-paying jobs above market (salary) and they tend to offer a full benefit package,” Walker said at a news conference.Flanked by Republican lawmakers from the area, Walker said that the company has committed to build the plant but that the state still is finishing negotiations on an incentive package.
