Recent updates

4/162017 - The 93-114th file has been updated. We have corrected numerious errors related to the ReportH, ReportS, PassH, PassS, MRef and Majority variables.

We have also added variables providing specific information about the committees of referral (ReferArr lists committees of referral) and committee assignments (SubCArr lists a member's committee assignments). Please contact with questions.

To be more specific, we discovered errors or omissions in some of the original json files used to create these variables

1. Incorrect committee code. Example: 94-HR-12972. The json file ( indicates that the bill was “Reported to House from the Committee on Public Works and Transportation with amendment,” but the committee code is incorrect: SSEV (code for the Senate Environment and Public Works).

2. Missing PASS_OVER information. Example: 98-HR-2464 ( Usually the json file indicates when a bill passes a chamber by specifying “status”:PASS_OVER:. However, for bills that pass the House by Unanimous Consent, status does not indicate that it passed.

The Congressional Research Service has also informed us that there may be errors for the PassS and PassH variables for the 93rd Congress.
