Randall Williams out after four contentious years as Missouri health director By Tessa Weinberg Missouri Independent Amid the peak of Missouri’s COVID vaccine rollout and just four years on the job, Randall Williams has stepped down as director of the state’s health department, effective immediately. Gov. Mike Parson’s announcement did not give a reason for Williams’ departure. Robert Knodell, Parson’s deputy chief of staff who has played a key role in the state’s vaccine distribution, will serve as acting director until a permanent replacement is found. “Dr. Williams has been a huge asset to Missouri, especially this past year in dealing with COVID-19,” Parson said in a written statement. “We greatly appreciate all the work he has done for the people of our state and wish him the best in his future endeavors.”
