JACKSON, Miss. (AP) -

A Mississippi man fighting a 60-year sentence for producing and distributing pornography featuring a 5-year-old boy argues that the prison term is unfair because his cooperation with authorities allowed for the breakup of child porn rings in Wisconsin and the Netherlands.

Brian Robinson of Potts Camp pleaded guilty in January 2012 to creating and distributing forms of child pornography on the Internet inside and outside the U.S.

The Justice Department says Robinson was arrested as part of a child porn investigation that has resulted in the arrests of 27 people and the identification of 138 child victims.

Robinson argues in filings with the 5th U.S. Circuit Court of Appeals that a federal judge failed to consider his cooperation with authorities in the U.S. and the Netherlands.

Oral arguments are scheduled for Monday in New Orleans.
