NEW YORK (Reuters) - The United States Olympic Committee (USOC) said on Monday it will not submit a bid to stage the 2020 Summer Olympics.

"We're not going to bid for 2020," USOC spokesman Patrick Sandusky told Reuters. "With such little time left we just didn't think we could put a winning bid together."

Rome, Tokyo, Madrid and Istanbul have already announced their intentions to bid.

After a failed attempt by Chicago to host the 2016 Olympics followed by a missed attempt to stage the 2022 World Cup, the U.S. expressed only mild interest in pursuing the 2020 Games.

The U.S. has been hesitant to re-enter the bidding process until it completes a contentious revenue-sharing agreement with the International Olympic Committee.

The dispute, over how to cut up global sponsorship revenues and U.S. broadcast rights, is believed to have been one of the key issues that scuttled Chicago's bid to stage the 2016 Games that went to Rio de Janeiro.

"That's a separate issue unrelated to bidding," said Sandusky. "We haven't been focused on bidding at all. We've been focused on the deal with the IOC and we continue to work on that deal with the IOC."
