The comments were overheard by other visitors who were concerned enough to alert jail staff, a release from the Cook County Sheriff's Department said.
Upon investigating, police say they learned Porter allegedly disciplined her 14- and 5-year-old children with physical violence, including knives. Authorities report neither child was enrolled in school.
Porter appeared in bond court Sunday, where she posted 10 percent of her $1,000 bond. Her next court date is set for July 19 in Maywood. The Illinois Department of Children and Family Services has taken custody of the two children.
