Ecclestone has now muddied the picture even further by answering "no, no" when asked if he is ruling out adding New Jersey to the 2014 calendar.
"They have a contract," he told Reuters, "so if they comply with the contract the race will take place.
"We would be very, very happy if it does," Ecclestone added.
An unnamed team boss suggested Ecclestone is playing his typical political games.
"It's not the first time we've heard words like these," the boss is quoted by Speed Week.
"I would not write off the race in New Jersey."
