Jared Fogle to plead guilty to charges related to child porn, source says

Former Subway spokesman Jared Fogle is expected to plead guilty to charges related to child porn, source tells ABC News.

Shortly after the news broke, Subway tweeted, "We no longer have a relationship with Jared and have no further comment."

Subway suspended its relationship with Fogle, 37, in early July after law enforcement agents raided his Zionsville, Indiana, home. The investigation was related to part of 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. Taylor faces eight felony charges including possession of child pornography. He did not enter a plea and waived a detention hearing.

At the time of Taylor's arrest, Fogle released a statement to the Indianapolis Star condemning Taylor.

"I was shocked to learn of the disturbing allegations against Mr. Taylor. Effective immediately, the Jared Foundation is severing all ties with Mr. Taylor," Fogle said in the statement.

Prior to news of the expected plea, no charges had been announced against Fogle. It was not clear if Fogle was the target of the investigation.

Fogle was first featured in ads for the company in 2000.
