House Speaker Scott Bedke, R-Oakley, said he hopes to have the rule introduced next week.
"We're floating drafts of the proposed rule around," Bedke said Tuesday. "We made a few changes, minor tweaks."
Bedke said the GOP caucus, which holds 57 of the 70 House seats, will discuss the rule establishing a standing Ethics Committee in a closed-door caucus Thursday.
The rule will go to House Judiciary & Rules Committee, Bedke said. It would be subject to approval by the full House.
Bedke has pressed for the change to help improve public perception and confidence after a series of ethical questions raised about lawmakers in recent years. In the past, ethics committees were empaneled after the lodging of a compliant and members appointed by the speaker.
If the committee is established it will have regular membership and would become the 15th standing committee in the House.
