Gov. Chris Christie says it's time for a New Jersey mayor under indictment to step down.

He said on the "Ask the Governor" show on the New Jersey 101.5 FM that Hamilton Township's John Bencivengo should resign.

He says that while the mayor has a presumption of innocence in court, he doesn't have an entitlement to a public office and that resigning would remove a cloud of suspicion from the town government.

The mayor was charged in April with attempted extortion for allegedly taking about $12,000 in bribes from someone seeking to maintain a contract with the township's school district.

Last week, a federal grand jury added a money laundering charge against the mayor.

Through his lawyer, he has denied the charges.
