"I have no idea what the problem was," Carper said.
He admitted that he had heard "rumblings" from sources that there may be problems at the agency.
"I heard that there was some dissention there, but I didn't know it was this bad," he said.
Hamilton was given a month's severance pay for her service when she was let go on Friday, Kees said, though he didn't know the exact amount.
He also claimed to not know Hamilton's yearly salary.
Kees said Friday's decision was difficult.
"It's always hard when you have to terminate someone."
Kees does not believe the move will affect the level of services offered by the agency.
Hamilton recently commented about Carper's move to look at transferring control of the senior nutrition program in Kanawha to a county agency.
Carper has become dissatisfied with the services provided by Putnam Aging, the agency responsible for providing meals to seniors in Kanawha. County staff members are now looking into Putnam Aging's service in the county.
Kees said Hamilton's termination had nothing to do with her comments in an article about Putnam Aging.
Carper does not believe Friday's decision to fire Hamilton will negatively affect the county's investigation into Putnam Aging.
"I'm not 100 percent sure it needs to be taken away from Putnam Aging yet," he said.
Carper added that if he did push for a transfer of control of the senior nutrition program, that agencies in the area other than Kanawha Valley Senior Services could bid on that program.
