Rapp is a counter-terrorism operative, employed, first unofficially then officially, by the CIA. The primary focus of the character is thwarting foreign terrorist attacks on the United States and he is presented as an aggressive operative who is willing to take measures that are more extreme than might be considered commonly acceptable.
