Agent Kellerman graduated from West Point fifteen years ago with a near-flawless record. He was almost immediately dispatched to Kuwait and because of the bravery and valor he demonstrated in combat in the first Gulf War, he became the first in his class to achieve the rank of captain. Kellerman had a promising career ahead of him in the Army, but the federal government noticed his potential and poached him, offering him a leadership position within the Secret Service.
Kellerman immediately went to work for Vice President Carolyn Reynolds' detail, carefully orchestrating her plan for securing the Presidency. Once Reynolds' gained the White House, Kellerman learned he would no longer be in her life. Bill Kim, a liaison was brought in and told Kellerman he would now report solely to him. Sensing a major distrust within the Administration, Kellerman realized he was being frozen out and turned rogue, partnering with Lincoln Burrows and Michael Scofield to bring down President Reynolds.
