We've recently gotten a few questions about our Congress API and when it will include new members elected in November.
The reason that these members are not yet in the Congress API is that most* new members will not take office until January 3, 2011 when the 112th Congress convenes. Because the 111th Congress is still in session we are waiting until these members are sworn in and have offices assigned to them to add them to the API. Rest assured though that we have begun work on tracking down all of the relevant information for the representatives and senators elect and should have a large update for the first week of the new year.
Note: Some individuals, such as Mark Kirk in Illinois were elected in special elections and have already been added to the API. To keep track of what changes have been made already look at our apidata repo.
