State Rep. Dan Kirby resigned Saturday — again — still insisting he "never sexually harassed anyone in the House of Representatives."

Kirby, R-Tulsa, had faced either expulsion from the Republican-controlled House or the loss of all legislative clout because of his conduct with a legislative assistant.

"I am proud of my accomplishments at the Capitol," Kirby, 58, told The Oklahoman on Saturday after submitting his resignation letter. "I served my constituents well. I was voted in ... five times. I can stand with my head held high knowing that I represented the district with integrity. I did a good job."

His letter stated the resignation was irrevocable and would be effective March 1. Gov. Mary Fallin will call a special election to fill the vacancy.
