"](CNN) - When President Obama delivers the commencement address at the U.S. Naval Academy on Friday, he will have a former presidential candidate and proud parent of one of the graduates in attendance.
John Sidney McCain IV, more commonly known as "Jack," will become the fourth McCain to graduate from the Annapolis, Maryland, service academy and the fourth with the same name.
About mid-day at the academy's commissioning and graduation ceremony, McCain will receive a Bachelor of Science degree, take the oath of office and be commissioned as an ensign in the U.S. Navy 103 years after his great-grandfather did the same.
