US President Barack Obama will travel to Copenhagen to support the bid by the city of Chicago to host the 2016 Olympic Games, the White House says, BBC reported.
Mr Obama will join his wife, Michelle, and others in his administration at the International Olympic Committee meeting in the Danish capital on Thursday.
Chicago faces opposition from Madrid, Rio de Janeiro and Tokyo in the vote.
