Byron York is a liar.

Or an idiot. Or both.

The swiftboat veterans in that year were the officers who served alongside John Kerry in Vietnam. They had first-hand knowledge of Kerry's service, and they had a story to tell about Kerry's behavior in Vietnam and his later antiwar activities at home.

Wrong.

None of those in the attack ad by the Swift Boat group actually served on Kerry's boat. And their statements are contrary to the accounts of Kerry and those who served under him.
