KANSAS CITY, Kan. (AP) -- A Kansas, City, Kan., man arrested as part of an international child pornography crackdown admitted that he traveled from Kansas to Missouri to have sex with a minor.

The Kansas City Star reports (http://bit.ly/Ze5ghJ ) Robert Poe III entered his plea Tuesday in federal court.

Poe was charged in August with three counts of traveling to entice a minor to engage in sex. He was accused of using a gun to force two boys to perform oral sex on him. Poe on Tuesday denied using a gun but said prosecutors had enough evidence to convict him.

Poe was arrested during a Homeland Security investigation that led to dozens of arrests.

He is a friend of 38-year-old Michael D. Arnett of Roeland Park, who pleaded guilty last week to making child pornography.
