A state senator is now calling on the governor to remove the director of South Carolina's child services agency. 

Richland County Senator Joel Lourie has been a frequent critic of  Department of Social Services Director Lillian Koller.

He says new numbers from internal reports show Koller is violating state law because nearly half of all children involved in reported abuse or neglect were not visited within 24 hours by a DSS caseworker. 

Lourie also says numerous foster children aren't being visited monthly by caseworkers, and about a half-dozen county offices were not audited within five years, as state law also requires.

“I'm using her numbers to show that the agency...is in complete meltdown right now.  The agency is in complete meltdown,” Lourie says.

Koller recently defended her agency when she testified before a legislative panel reviewing complaints about DSS, and she has released a new statement disputing Lourie's claims.

Governor Nikki Haley also released another statement expressing her confidence in Koller's handling of DSS, and calling Lourie's concerns “political.”
