ATLANTIC CITY - Pressure is building on New Jersey lawmakers to agree on a ballot question to put before voters asking whether to approve two new casinos in the northern part of the state.

Two unions supporting state Senate President Steve Sweeney, himself a union official, criticized Assembly leaders for failing to support Sweeney's bill.

The Senate bill would require both new casino licenses go to existing Atlantic City casino operators, while the Assembly would apply that requirement to only one.

Assembly Speaker Vincent Prieto says his bill represents a good compromise between the needs of Atlantic City and the rest of the state.

Senators Raymond Lesniak, a Democrat, and Joseph Kyrillos, a Republican, called on lawmakers to agree on a single plan for the November referendum.
