Zach is a White House staffer who is friends with Donna Moss. His job includes recording news feeds, suggesting he works in the Communications Department, and he helps Donna when she realizes the B-roll of Howard Stackhouse's family only shows six grandchildren when he has seven.[1] He participates in her prank on C.J. Cregg when C.J. is interrogating staffers about a leak, at first pretending to be on C.J.'s side but then joking about witch hunts.[2]
