The youngest son of Sen. John McCain (R-Ariz.), a former prisoner of war in Vietnam and a vocal proponent of more American troops in Iraq, will soon report for duty in the Marine Corps, Time magazine reported.
Jimmy McCain, 18, will spend three months in boot camp in California this fall and another month in specialized training.
Depending on his unit, the younger McCain could wind up in Iraq or Afghanistan, where Marines have experienced heavy fighting and casualties.
Sen. McCain's family has a military tradition. His grandfather and father were both Navy admirals. McCain was a Navy fighter pilot when he was shot down over Vietnam. He spent more than five years in captivity. McCain's other son, Jack, attends the U.S. Naval Academy.
About 1% of members of Congress have children serving in the military.
