TRENTON, N.J. — A former New Jersey lawmaker who championed legislation fighting child pornography will be sentenced for viewing nude images of underage girls.

Neil Cohen could be sent to prison for five years Monday.

Cohen acknowledged viewing and printing images meant for sexual gratification from a computer in his former legislative office.

He left at least one image at a receptionist’s desk, leading to the investigation and charges.

Cohen will be required to register as a sex offender under Megan’s Law and be subject to lifetime supervision by the Parole Board.

The ex-assemblyman agreed never to seek public office again. He is likely to be disbarred.
