JONESBORO, Ill.—A civil lawsuit alleging ethics violations nearly a decade ago has become an issue in a Democratic congresswoman’s bid to unseat first-term Republican U.S. Sen. Mark Kirk in what is expected to be one of the country’s most competitive 2016 Senate races.
The complaint alleging workplace retaliation was filed by two employees of a southern Illinois veterans’ home against Tammy Duckworth, now a Chicago area congresswoman who at the time led the Illinois Department of Veterans Affairs.
