Simon Donovan was a law enforcement officer and Secret Service agent who was assigned as a temporary protection detail for White House Press Secretary C.J. Cregg, after she received e-mail death threats during the spring of 2002.
Donovan attended college on a military scholarship and served a number of years in the Army, after which he spent time employed in the Chicago Police Department before joining the US Secret Service. He was present in Rosslyn during the attempted assassination of Charlie Young, being the one to shoot and kill would-be-assassin Ray Beckwith. Later on he was assigned to C.J. Cregg's protection detail, the two of them constantly at odds over the level of protection she required. Shortly after C.J.'s stalker was apprehended, he was shot and killed in New York City while attempting to foil an armed robbery in a convenience store.
- Donovan states that he attended college "basically on an Army scholarship" and is later seen wearing a West Point sweatshirt, indicating that it was his alma matter.
- Robert Ritchie's dispassionate reaction to Donovan's death ("Crime...boy, I don't know") served as Bartlet's motivation to thoroughly defeat him in the 2002 election.
