To undecided IOC members, Chicago's bid chairman is making a simple pitch.
"As you look at everything that you have seen and heard from each of the four cities, who'll be the best partner? Who'll be the most reliable partner?" said Patrick Ryan, Chicago 2016 chairman.
"They have to perform their best bid, that they have the best to show to the IOC. Members and then we're ready for the judge to show the score. Is it a 10 or a 9.95? We don't know what is going to happen," said Nadia Comaneci, Olympic gymnast.
Obama criticized for going to Copenhagen
Critics of President Obama's trip to Copenhagen say now is not the time for him to lobby for the Olympics.
The president leaves on Thursday.
"I've got so much to do here. I will sleep on the plane. I will land and speak," said Obama.
Those comments came as President Obama met with Nato's secretary general at the White House Tuesday.
Previously, the president said health care reform would keep him from Copenhagen.
On Tuesday, Republican National Committee chair, Michael Steele, questioned the president's priorities. The White House laughed off that notion.
ABC7 will provide complete coverage of the announcement. A timeline of coverage can be found here. Ben Bradley will report live from Copenhagen starting Tuesday.
On October 2, the host city winner announcement is expected at about 11:30 a.m.
All of events will also be streamed live on our Web site, abc7chicago.com.
