IRAQ: War as a family affair, Part 3

The U.S.-Iraqi army training camp at Habbaniya is about 60 miles from Baghdad, and so few U.S. officials or politicians make the trek.

One who did was Sen. John McCain (R-Ariz.) who visited in December to be with son, Jimmy, an enlisted Marine in his first tour in Iraq. No press was allowed, in keeping with McCain's policy of never appearing to use his son's service as a prop for his presidential bid.

The younger McCain is back in the U.S. now, after finishing his seven-month deployment.
