Factual error: In the first shot after the recap, the overlay text reads "United States Capitol/Sunday/Inauguration Day". During this episode and the one that follows there is an inauguration day celebration and President Bartlet makes his inauguration speech. Historically, however, when inauguration day falls on a Sunday the celebrations and speeches are scheduled for the next day, a Monday. The president is still sworn in on inauguration day (March 4th until 1933, January 20th after that), but all other activities are moved back one day. The inauguration date has only fallen on a Sunday 6 times since 1798, and only twice since the current inauguration date was set, so it is understandable that this arcane but important bit of scheduling tradition was missed by the show's researchers.
