Ohio Republican Gov. Mike DeWine is expected to name Lt. Gov. Jon Husted to fill the US Senate seat recently vacated by Vice President-elect JD Vance, two sources with knowledge of the decision told CNN.

Gov. Mike DeWine must appoint a new lieutenant governor. Meanwhile, who'd step in as acting governor in the event he's unable to fulfill his duties?

J.D. Vance had four years left on his Senate term before he resigned from his seat. Jon Husted is expected to take his place.
