Seneca Nation of Indians President Robert Porter today called on the state to recognize a nine-year-old gaming accord that they say gave the nation the exclusive right to operate casinos in western New York.

“We strongly believe that allowing commercial gaming interests to operate in the areas of Western New York where the Seneca Nation has gaming exclusivity will undermine the economic stability of the region, and actually result in a net negative impact on the people and communities of Western New York,” Porter said.

Porter testified in Canandaigua, Ontario County, before the Senate Committee on Racing, Wagering and Gaming. The Senecas say they’re holding $310 million in escrow in payments due to the state after paying nearly a half billion to Albany.

The Senecas operate two casinos, including one under construction in Buffalo. Gov. Andrew Cuomo last month said he would be open to a constitutional amendment that would allow for non-Indian gaming in New York.

Notably the Senecas did not issue a statement decrying the governor’s statement.
