A U.S. Senator will be passing through the area this week. As part of Senator Grassley’s annual tour of the 99 counties in Iowa, he’ll be stopping at the Columbus Junction City Hall from 9 to 10:15 on Tuesday morning. Senator Grassley says he encourages residents to bring questions and concerns to the town hall meeting. Grassley has been doing his tour of the counties in Iowa since he was elected to the Senate in 1981.
