Indiana Department of Child Services Director Mary Beth Bonaventura is resigning her position by the end of the month.
In a resignation letter to Gov. Eric Holcomb, Bonaventura said the governor's staff is cutting her budget and services in the midst of the opioid crisis.
The letter begins by outlining the department's successes since then-Gov. Mike Pence appointed Bonaventura in 2013.
"Despite these and many other accomplishments, I am now in the untenable position of seeing Hoosier children being systematically placed at risk without the ability to help them," Bonaventura writes. "I choose to resign rather than be complicit in decreasing the safety, permanency, and well being of children who have nowhere else to turn."
Bonaventura writes that the current chief of staff has created a "hostile work environment" by bullying subordinants and making cost-cutting decisions without "regard for the consequences."
