City Manager Lori Curtis Luther told the station she was prepared to pursue his removal from the EOC, but he resigned.
"I am very pleased that he resigned. I was personally appalled and disgusted by the comment that I found to be blatantly racist," Luther said.
Teri Downing, staff liaison to the Beloit EOC, said the city had not had time to fully investigate the comment before the former chairman resigned.
The commission has the opportunity to schedule a special meeting to elect a new chair. If not, a new chair will be appointed at their next meeting on Dec. 21.
