"We have a contingency plan if Obama comes in," said Kai Holm in an interview with the Olympic publication, Around the Rings. He also said the Danish government is handling the security operation and would foot the bill.
Holm said he has heard 1,000 people tied to Chicago 2016 could come to Copenhagen should President Obama make the trip to lobby for his hometown. That includes President Obama's Secret Service agents.
Madrid, another bid city, is expected to bring about 700 people to Copenhagen for the start of the session.
Rio de Janeiro and Tokyo are also in the running to host the 2016 Olympics.
The vote to determine the 2016 host will be in Copenhagen on October 2.
