Former Subway Spokesman Jared Fogle Expected to Plead Guilty to Charges Related to Child Porn, Source Says

— -- Jared Fogle, the former Subway spokesman, is expected to plead guilty to charges related to child pornography, a source with knowledge of the situation told ABC News today.

Fogle, 37, gained national fame when he lost a significant amount of weight by eating turkey and vegetable sandwiches from Subway and exercising. He was first featured in ads for the company in 2000.

Subway suspended its relationship with Fogle in early July after law enforcement agents raided his Zionsville, Indiana, home as part of what two sources briefed on the investigation told ABC News was an ongoing investigation into child pornography.

The officials told ABC News that the investigation was an offshoot of the May arrest of Russell Taylor, the then-executive director of Fogle's charity devoted to children's health.

Fogle's attorney Ron Elberger told ABC News today he had no comment.

Subway said in a tweet: "We no longer have a relationship with Jared and have no further comment."
