U.S. Senator Chuck Grassley made a stop in Knoxville this week on his 99 county tour to keep in touch with Iowans. Grassley met with the Knoxville Noon Kiwanis club during their monthly meeting at the Swamp Fox Thursday. He says these face-to-face meetings give him the chance to answer questions and get information, feedback and comments from a wide cross-section of Iowans. The Republican from New Hartford has served in the Senate since 1981 and has held a constituent meeting in each of Iowa’s 99 counties since being elected.
