LINCOLN, Neb. (AP) — A legislative committee is telling an embattled Nebraska senator to resign by Friday or face consequences that could include expulsion from office.

The Legislature’s Executive Board voted 9-0 Monday to send a letter to Sen. Bill Kintner of Papillion calling on him step down. Kintner was fined $1,000 for misuse of state property after admitting that he engaged in cybersex on a state laptop with a woman he met online.

Kintner has rejected previous calls for his resignation from high-ranking officials, including Gov. Pete Ricketts and Speaker of the Legislature Galen Hadley. Executive Board members say they’ll reconvene on Sept. 8 if he declines again.

The vote came after a hearing in which some conservative activists defended Kintner.

A Kintner staffer says the senator will respond in a statement.
