Another similarity between Aaron Sorkin's Newsroom and the West Wing is the use of the Ave Maria. It played in the background of Will and Mac's wedding as well as in the first season of the West Wing with Josh and CJ.
"Kundu" is the country mentioned in the confidential documents, however it is a fictitious country. Aaron Sorkin also used this fake nation in his series, the West Wing.
Don Keefer talking to Mac says we shot the hostage when talking about Will and the case. Jeff Daniels tells Keanu Reeves to shoot the hostage in Speed.
