Steve Corsi, director of Missouri Department of Social Services, has turned in his resignation.
Corsi's last day is to be June 3, assuring enough time for the administration to find a new leader for the department.
Former Gov. Eric Greitens appointed Corsi, who arrived after having served as the director of Wyoming's Department of Family Services, in June 2017.
He went from running a Wyoming department with a staff of about 700 people and a budget of $258 million, to the Missouri department with a staff of 7,000 and budget of $9.6 billion.
During budget hearings in February 2018, his unusual salary arrangement came under scrutiny. It was revealed Corsi received a salary of $128,244 per year from his department, while also receiving $13,756 from the state Department of Health and Senior Services, making his total $142,000.
The Greitens administration briefly defended the arrangement, but within days said it ended the practice. However, Corsi continued to receive the double payment the following month. Corsi said as soon as he learned of the extra payment, he went to the state to get it corrected.
A Thursday news release from Gov. Mike Parson's office said Corsi is leaving the state job for a new opportunity with a faith-based nonprofit organization. The organization has not been identified.
Within his resignation letter, Corsi thanked Parson for his faith and graciousness.
"Your words at the Governor's Prayer Breakfast and nearly every time I see you remind me that the Master is in charge and we need to always seek Him," Corsi wrote.
Parson's news release said the administration will work over the next few weeks to find leadership that will assure the department builds on reforms it has already made.
