During the third season, C.J. receives a series of death threats, which leads to her being placed under the protection of Secret Service agent Simon Donovan (played by Mark Harmon), with whom she becomes romantically involved. Shortly after going off-duty, Donovan is shot and killed after becoming caught up in the armed robbery of a New York City grocery store in the episode "Posse Comitatus". C.J. also has a long on-again, off-again relationship with the "Washington Post"'s White House correspondent Danny Concannon, although C.J. feels that they should not date because it would be a conflict of interest with her job. In the seventh season (when C.J. has become chief of staff and no longer deals with the press on a daily basis) the subject is slowly revisited. At series' end, she and Danny are learning how to have a romantic relationship with each other.
