Scientific Games Corporation, a top rival to IGT, has joined the intense battle over which company will provide video and lottery services to the state of Rhode Island.

A filing with Secretary of State Nellie Gorbea’s office shows that Las Vegas-based Scientific Games has signed up Leonard Lopes as a lobbyist. The company is expected to hire additional lobbyists, The Public's Radio has learned.

Lopes referred comment to Scientific Games.

“We have retained a representative to monitor the Rhode Island bidding situation," Susan Cartwright, a spokeswoman for the company, said via email. "Scientific Games, as the leading U.S. based supplier of casino and lottery products globally, including the primary supplier to 9 of the top 10 highest performing instant ticket lotteries in the world, would be excited to compete for the opportunity to supply our record-breaking products to maximize revenue for taxpayers and beneficiaries of Rhode Island.”

IGT and Twin River, the two companies fighting over Rhode Island’s gambling business, have already enlisted a large number of prominent lobbyists.

In a brief statement, Twin River spokeswoman Patti Doyle said, "As we previously stated, we have had conversations with Scientific Games about a possible partnership should the state decide to enter into an open, competitive process for this gaming contract."

The lobbying lineup for IGT includes company execs Donald Sweitzer and Michael Mello, as well as Robert Goldberg, Andrew Annaldo, Peter Baptista, Erich Haslehurst, Gayle Wolf, Kevin Horan, and Stephanie L. Federico. For Twin River, the names include George Caruolo, Chris Boyle, R. David Cruise, William Murphy, Mark Ryan, Matt Jerzyk, Will Farrell, and Twin River execs Marc Crisafulli, John Taylor and Craig Eaton.

Scientific Games’ entry to the debate comes amid debate over whether the state should extend IGT’s contract, a move supported by Gov. Gina Raimondo, or open the contract to additional bidders.

Raimondo has argued that the value of keeping IGT and 1,100 jobs in Rhode Island, as part of what she calls an improved contract, is better for the state than risking the loss of IGT.

Critics say it’s impossible to know what the best deal is if the state doesn’t consider competitors to IGT.

The House is expected to hold hearings on the deal supported by Raimondo later this year.
