Former subway spokesman Jared Fogle allegedly asked a reporter to put hidden cameras in her children's rooms.

Rochelle Herman began recording conversations with Fogle for the FBI, after he told her that "Middle School girls were so hot," according to CNN.

"I was in shock ... I actually was questioning, 'Did I really just hear what I think I heard?' I looked over at my cameraman ... and he was just astounded," she said.

Fogle was attending a health event at a school in Florida back in 2007 when he first said those words to Herman. It started as just a random comment but turned into a full on investigation.

He later tried to persuade the reporter to allow him to watch her children with hidden cameras.

"I had two young children at the time, and he talked to me about installing hidden cameras in their rooms and asked me if I would choose which child I would like him to watch," she said.

The celebrated subway spokesman is facing up to 12 and a half years in prison for pleading guilty to child pornography charges, including crossing state lines to pay for sex with minors.

"He talked about sex with underage children. It was just something that he really, really enjoyed," Herman said.

The reporter worked undercover with the FBI for years to gather evidence against Fogle by wearing a wire to record their conversations.

"He trusted me for unknown reasons," Herman told CNN's "AC360." "He had said to me numerous times over the course of years about having sex with minors."

The investigation also led authorities to Russell Taylor, a former director of Fogle's charity that focuses on children's health, who is now facing child pornography charges as well.
