Here is John Diehl’s resignation statement. It does not say when he is stepping down
“In my time in the General Assembly, I’m proud of my long legislative legacy that was built upon being honest with members and doing what is in the best interest of our caucus and this body. I am proud to have led us to the largest Republican majority in state history, the first income tax cut in nearly one hundred years, and an override of the governor’s veto of Missouri’s congressional redistricting map.
I have acknowledged making a serious error in judgment by sending the text messages. It was wrong and I am truly sorry. Too often we hear leaders say they’re sorry but are unwilling to accept the consequences. I understand that, as a leader, I am responsible for my actions and I am willing to face the consequences.
I appreciate those who have stood beside me and the overwhelming number of caucus members that have offered continued support; but for the good of my party, the caucus, and this state, I’m not going to further jeopardize what we have accomplished this year and what can be accomplished in the future. Therefore, I will be resigning the position of Speaker of the House and the office of State Representative in a way that allows for an orderly transition.
