McCain's Vietnam Captor Speaks: A Conversation With Tran Trong Duyet

In 1967, US presidential candidate John McCain's plane was shot down on a bombing mission over North Vietnam.

BBC reporter Andrew Harding tracked down the man who held him captive in a Hanoi jail for five years.

"McCain is my friend," said 75-year-old Tran Trong Duyet. "If I was American, I would vote for him."
