In this Feb. 8, 2017, file photo, Iowa state Sen. Mark Chelgren, R-Ottumwa, poses for a photo at the Statehouse in Des Moines, Iowa. Chelgren said March 2, 2017, that he didn't mean to mislead anyone by claiming he had a business degree from a company that actually had awarded him a certificate for participating in a training program when he worked at Sizzler.
