President Barack Obama has written a letter telling International Olympic Committee members that the United States would "welcome the world with open arms" if Chicago is awarded the 2016 Summer Games.
In a letter obtained by the Associated Press Tuesday, Mr. Obama added that "the City of Chicago is designed to host global celebrations and it will deliver a spectacular Olympic experience for one and all."
The letter, which is dated September 10, raises the possibility of Obama going to Copenhagen to support Chicago's bid at the vote on October 2. If Chicago wins the bid it will be the first time the United States has hosted the Summer Games since Atlanta in 1996.
But the Windy City - Chicago - is facing stiff competition from three other prospective hosts: Rio de Janeiro, Tokyo and Madrid. The president's appearance in Copenhagen, which will also be visited by Brazilian President Luiz Inacio Lula da Silva and Spanish King Juan Carlos, could be the push needed to put the United States' bid over the top.
