TRENTON, N.J. — Former New Jersey Assemblyman Neil Cohen has pleaded guilty to endangering the welfare of a child by distributing child pornography.

The Democrat was accused of using computers in his Union County legislative office to view, print and duplicate images of underage girls simulating or engaged in sexual acts.

As an assemblyman, Cohen championed bills aimed at fighting child pornography.

Under terms of the plea agreement, prosecutors will seek a 5-year prison term when Cohen is sentenced. The 59-year-old would also have to register under Megan’s law.

Cohen checked himself into a psychiatric hospital after giving up his Assembly seat in 2008.
