CHICAGO (AP) — A former Illinois state representative has pleaded not guilty to child pornography charges.

Keith Farnham entered the plea Tuesday at a federal courthouse in Chicago.

The 66-year-old Elgin Democrat was charged in a criminal complaint in April with possessing child pornography.

A federal grand jury returned an indictment last month charging him with possessing, receiving and transporting child pornography.

He’s been ordered confined to his home during the case and is even barred from stepping onto his patio.

The initial criminal complaint alleged that Farnham possessed videos depicting child pornography on a computer. The document also provided graphic details about images allegedly sought and traded by Farnham online. Some allegedly showed children under 10.

Farnham resigned in March after five years in the Illinois General Assembly.
