US President Barack Obama has been pictured wielding a Star Wars lightsaber toy at a fencing demonstration on the White House lawn.
The fencing was part of a promotion for Chicago's bid for the the 2016 Olympic Games.
"Chicago is ready. The American people are ready. We want these Games," President Obama said during the demonstration.
The International Olympic Committee (IOC) members will decide the host city for the 2016 Summer Games on October 2 in Copenhagen.
