It was something of a faux pas that the First Lady didn't attend the funeral of a former President with her husband.
Diana Douglas is the mother of actor Michael Douglas with whom Martin Sheen is close friends.
When the president is visiting the Lincoln Memorial at the end of the episode he appears to be completely alone. Normally, there would be secret service agents not far away.
This is the second time we see Gus Westin, Bartlet's grandson, but the first time the character gets any real screen time or lines. The first time we see him is in "7A WF 83429."
Goof: On Day 3 of Shutdown, the team are eating pizza in the "war room". CJ takes a large bite but in the next shot over her shoulder we see a complete piece of pizza.
Jed talks about a basketball game between Providence and Notre Dame, but both teams are in the Big East conference where conference matchups rarely occur this early in the season.
Jed replaces the lid on the peanut butter jar and the camera pans to Abbey. When the camera pans back to Jed, the lid is no longer on the jar.
Matthew Perry received an Emmy nomination in 2004 for his portrayal here of Joe Quincy.
Bartlet: Say, you think he'll mention the rise in German unemployment might be tied to our bombing the Qumari pipeline?
Qumar is a made-up country.
Amy tells Josh a joke about a man who hasn't eaten in 38 days because he was waiting for his mother to call. This joke is also used in Studio 60, another Sorkin show, where Harriet Hayes has trouble remembering the right way to tell the joke.
Josh finds a dead fish wrapped in newspaper in his office. There is a rumour that Rahm Emanuel, Member of Congress for Illinois, sent a dead fish to a colleague with whom he was on bad terms.
Although Josh Lyman makes a lot of insulting Wisconsin jokes, Bradley Whitford is actually from Wisconsin.
When Zoey was kidnapped in the last season the date was May 7. We know this from the piece of paper that Charlie had in his wallet for the champange bottle celebration with her. During this episode she is clearly still suffering from the trauma and C.J. is covering her return as if she was found a week or two before. This would be just fine if the episode wasn't based around the Fourth of July which is a whole two months later!
H. Richard Greene plays Robert Royce, the Senate Majority Leader. However in a previous episode he played a moderate Republican Representative in the House. It is very unlikely that a moderate Republican would switch over to the Senate and be made the Majority Leader so quickly.
When the staff is discussing the Speaker's list of vice presidential candidates and the political ramifications, Bartlet exclaims, "Come on people, the door is closed!" meaning let's be honest about our motives, because no one else can hear us. But in the next shot the door is open!
Leo: Oh, I don't think all Qumaris.
Qumar is a made-up country.
The title of this episode is not mentioned in this episode but the one before it, "7A WF 83429." The possibility is high that these two episodes were meant to air back-to-back as the two-parter that they are.
Leo: Your government actively supports the Bahji.
The Bahji terrorist cell is made-up.
The attack took place at 1110 Zulu Time, and the President was informed at 6:30 a.m. Eastern Time. During Daylight Savings Time, Eastern Time is only four hours behind Zulu (Greenwich Mean) Time.
In this episode we finally learn where the fictional country of Qumar is located. On the map on the Situation room wall, Qumar is shown to be cut out of Iran with a coast line.
