DENVER: Chicago officials tried to distance themselves on Monday from a revenue-sharing dispute between the International Olympic Committee (IOC) and United States Olympic chiefs that is threatening to derail the city's bid to stage the 2016 Summer Games.

Chicago 2016 Chairman and CEO Pat Ryan, however, moved quickly to get the bid back on track, saying he had invited US President Barack Obama to be part of the final presentations in Copenhagen ahead of the Oct. 2 vote to pick a host.

"I saw him (Obama) twice the last few months and did mention his support for the bid," Ryan told reporters. "We know that he wants to support our bid and that he would likely be there if he could be there."
