ABC: If guilty, Foley could be sentenced to years in prison

Foley shit.

They say he used the screen name Maf54 on these messages provided to ABC News.

Maf54: You in your boxers, too?
Teen: Nope, just got home. I had a college interview that went late.
Maf54: Well, strip down and get relaxed.

Another message:

Maf54: What ya wearing?
Teen: tshirt and shorts
Maf54: Love to slip them off of you....

The language gets much more graphic, too graphic to be broadcast, and at one point the congressman appears to be describing Internet sex.

Federal authorities say such messages could result in Foley's prosecution, under some of the same laws he helped to enact.

"Adds up to soliciting underage children for sex," said Brad Garrett, a former FBI agent and now an ABC News consultant. "And what it amounts to is serious both state and federal violations that could potentially get you a number of years."
