A Long Island company is suing New York state, arguing that it lost out on a multimillion-dollar contract because its competitor donated large sums of campaign cash to the governor.

Elliot Bloom of Long Island Clean Tech, LLC says his company was set to create more than 1,000 local jobs. It had won a state request for proposal, or RFP, to develop a parcel of land at Long Island Republic Airport in Farmingdale.

But a year later, the state put out a new RFP and instead chose Stratosphere Development, an affiliate of Talon Air.

In a lawsuit filed last month, Clean Tech says the state created an uneven playing field.

Bloom says Stratosphere donated more than $200,000 to Gov. Andrew Cuomo during his first term in office, making it one of his largest campaign contributors.

"We find it hard to believe that those campaign contributions didn't play a role here," he says.

But a spokesperson for the Empire State Development Corporation says the assertion that campaign contributions played a role in the state's decision is wrong.

"Clean Tech's suit consists of baseless, frivolous allegations by a disgruntled bidder who failed to make good on key provisions of the RFP and ignored our good-faith attempts to work with them," the spokesperson says. "This process was fair, equal and transparent to all applicants."

The spokesperson is also accusing Clean Tech of continuing to "waste the public's time on sour grapes."
