NEW YORK: President Barack Obama is having some fun at the expense of those who criticized him for trying to help his Chicago hometown land the 2016 Summer Olympic Games.

Addressing donors at a Democratic Party fundraiser Tuesday night in New York City, Obama said he believes in a strong opposition but doesn't like it when some folks root for him to fail on health care or ... on getting the Olympics.

In a mocking tone Obama said: "Who's against the Olympics? What's up with that?"

Some Republicans criticized Obama for flying to Denmark earlier this month to boost Chicago's Olympics bid. Critics said he should have stayed home to deal with health care, unemployment and Afghanistan, among other issues.

Brazil won the right to host the Games.
