This afternoon, via Twitter:
Governor Mike Parson @GovParsonMO
Honored to appoint Mike Kehoe as the next Missouri Lt. Gov — This is an important position, not just because of duties assigned by MO law & the state constitution, but also to reassure Missourians that all operations of state government will continue. #MissouriForward

Interestingly, there’s no announcement (as of this posting) on the Governor’s web site.
