McCain is set to show his Navy pride.

ANNAPOLIS, Maryland (CNN) – Republican presidential candidate John McCain made a stop Saturday at his 50-year class reunion at the U.S. Naval Academy football game.

The Arizona senator, who often mentions his time as a prisoner of war during the Vietnam era, graduated from the Academy in 1958, along with fellow alumni John Poindexter and Robert “Bud” McFarlane—two consecutive national security advisers serving under President Ronald Reagan who both played a role in the Iran-Contra affair. McCain's son, Jack, is currently a senior at the Naval Academy.

The Navy Midshipmen (1-2) play the 0-2 Rutgers Scarlet Knights.

UPDATE: McCain and wife Cindy appeared to have left earlier than planned, as staff and U.S. Secret Service traveling with the press pool were caught off guard. The White House hopeful stayed long enough to see only the first quarter before he departed.
