LINCOLN, Neb. (AP) — A conservative Nebraska state senator has agreed to pay a $1,000 fine for engaging in cybersex with a woman on his state computer.

Sen. Bill Kintner of Papillion acknowledged Friday that he accepted the woman’s invitation while on a trip in July 2015. When the encounter ended, Kintner says she tried to extort $4,500 from him by threatening to release a video of him.

Kintner says he then contacted the Nebraska State Patrol and confessed to his wife.

The Nebraska Accountability and Disclosure Commission imposed the $1,000 fine in a settlement after finding that Kintner improperly used his state computer.

Gov. Pete Ricketts and Speaker of the Legislature Galen Hadley called on Kintner to resign. Kintner says he plans to remain in office, but he could be impeached or expelled.
