US cyclists sorry for wearing masks

The US cyclists, who walked out of Beijing airport wearing masks on Tuesday, have apologized for their behavior.

Michael Friedman, Sarah Hammer, Bobby Lea and Jennie Reed issued a statement yesterday saying: "We deeply regret the nature of our choices. Our decision was not intended to insult BOCOG (Beijing Olympics organization committee) or countless others who have put forth a tremendous amount of effort to improve the air quality in Beijing."
