SALT LAKE CITY (AP) — Utah lawmakers on Wednesday demanded the resignation of Sen. Gene Davis, a sixth-term Democrat facing sexual misconduct allegations, including for inappropriately touching a former intern who was in college at the time.

Leaders in the Republican-controlled Senate announced plans to immediately strip Davis of his committee assignments. Davis’ five Democratic colleagues subsequently announced they had accepted his resignation from their caucus. Lawmakers from both parties demanded he resign.

“We strive to create and maintain to have a respectful and professional work environment and are committed to addressing any allegations,” Senate President Stuart Adams said in a statement.

The actions were prompted by an independent investigation into Davis’ conduct commissioned after allegations surfaced in August that he had touched a former intern on the waist and toes at the Statehouse, where she worked for him. The investigation determined that it was “more likely than not” that Davis invaded the personal space of former intern Sonia Weglinski, who posted publicly about Davis’ conduct on Instagram.

The investigation also accused him of not being forthcoming or completely honest and determined that he “likely violated the Legislature’s Workplace Discrimination and Harassment policy.”

Davis, 77, was defeated in the Democratic Party’s June primary. The allegation brought on broad condemnation from lawmakers and political groups, including the Utah Democratic Party and the Salt Lake County Democratic Party. It’s also ensnared campaign staff and party officials, who were accused of either knowing about the misconduct or not having procedures in place to act quickly upon becoming aware.

Davis did not immediately respond to a phone call requesting comment.

Davis resigned later Wednesday evening.
