RED WING (AP) — The mayor of Red Wing says he will resign amid public pressure over his second job as a frack sand lobbyist.

Mayor Dennis Egan said he could have legally continued on as mayor while he worked as the executive director of the Minnesota Industrial Sand Council. But he says he'll resign April 1 because his second job had become a distraction.

Red Wing City Council member Peggy Rehder says a special election for Egan's replacement will be discussed Monday. The City Council will drop its plan to investigate Egan's business dealings with the frack sand industry.

Red Wing is in frack sand territory. Demand for silica sand is high because it's used in hydraulic fracturing, or "fracking," that produces oil and gas.
