TOPEKA, Kan. (AP) — Republican incumbent Pat Roberts and independent candidate Greg Orman are holding multiple events across Kansas as they run for U.S. Senate.

Roberts launched what he called a listening tour this week, promising to visit all 105 counties. He stopped Wednesday in south-central Kansas for a Wichita forum on small-business issues and town hall meetings in Derby and Andover.

Orman was on an 18-stop bus tour that took him Wednesday to Hays, Colby and Garden City.

Roberts is seeking his fourth, six-year term in the Senate. Orman is an Olathe businessman and the co-founder of a business capital and management services firm.

The Democratic nominee is Shawnee County District Attorney Chad Taylor.
