The chairman of Oklahoma's Department of Human Services announced his resignation Tuesday.
Brad Yarbrough gave the news of his departure Tuesday morning after a regularly scheduled commission meeting, citing "an excessive investment of time."
"It has been a privilege to serve as Chairman these past eight months," Yarbrough said in a press release. "I accepted at a time when the DHS faced many significant challenges ... Business opportunities and personal priorities now require more attention. To adequately accommodate, it's necessary to resign as Chairman."
He was appointed to the position by Gov. Mary Fallin in Sept. 2011. He will remain on as a member of the commission.
The OKDHS has been heavily scrutinized in recent years and is undergoing significant alterations as the result of legislation passed by Fallin in May.
Among other things, the organizational structure of the agency's child welfare division and the process of director's appointments will change, with Senate confirmation. Another measure would allow voters to decide whether to abolish the governing board.
