INDIANAPOLIS — A new leader has been named for the Indiana National Guard, a month after his predecessor resigned under pressure following claims that he retaliated against a staffer for reporting his alleged affair with a subordinate.

Gov. Eric Holcomb’s office announced Tuesday that Col. R. Dale Lyles will become Indiana’s adjutant general and promoted to brigadier general effective Oct. 1. Lyles is a 32-year military veteran who most recently has been deputy chief of staff for operations at the National Guard Bureau in Washington.
