NEW YORK (AP) — Company officials at daily fantasy sports website FanDuel have vowed to keep their New York operations running after the state’s top lawman told them to stop.

FanDuel CEO Nigel Eccles told reporters Wednesday that their 500,000 customers in New York should keep playing.

The reaction comes a day after New York Attorney General Eric Schneiderman sent FanDuel and rival DraftKings cease-and-desist letters. He says their companies violate state gambling laws and are games of chance, not skill.

The companies have five days to try to persuade Schneiderman that their operations are lawful. It’s not clear what will happen after those five days pass.

DraftKings legal adviser Martha Coakley says Schneiderman’s legal analysis is flawed. She says the company will challenge it.

Coakley was formerly attorney general of Massachusetts.
