OKLAHOMA City — The dominoes are still falling at the Oklahoma State Department of Health after flaws were found in the budget.
Deborah Nichols, the chief operating officer, resigned this week.
Commissioner Terry Cline and Senior Deputy Commissioner Julie Cox-Kain also resigned less than a month ago.
Gov. Mary Fallin selected Preston Doerflinger to take Cline's place. He says after taking over the department he discovered the agency's practices had created a $30 million budget shortfall.
The turnovers follow accusations that the agency's top officials used "accounting tricks" to falsely present a balanced budget since at least 2011.
Oklahoma Attorney General Mike Hunter has requested a state investigative audit of the department, which could lead to criminal charges.
