From the Drudge Report:
His next trip down, a reporter and a camera crew were allowed to follow along on skis — just in time to see Mr. Kerry taken out by one of the Secret Service men, who had inadvertently moved into his path, sending him into the snow.
When asked about the mishap a moment later, he said sharply, "I don't fall down," then used an expletive to describe the agent who "knocked me over."
Such class. And Carter/Hillary-esque to boot.
