Many states and municipalities restrict campaign finance contributions by contractors. D.C. law has no such restrictions. Sort the data below to see what percentage of contractors' donations came within one year or within two years of contract approval.

Methodology

WAMU and the Investigative Reporting Workshop obtained legislative records to analyze more than 1,000 contracts that were sent to the D.C. Council for approval from 2007 through January 2014. The reporters also analyzed more than 100,000 campaign contributions to D.C. officials and candidates from the Office of Campaign Finance from 2005 through January 2014. This allowed us to capture contributions made two years before or two years after votes on the contracts.

The database includes donations from contractors, their employees and their family members.

The database has limitations. While city law requires individuals to disclose their employer when making campaign contributions, WAMU found this information on less than half of the donations on file with the Office of Campaign Finance. To identify the employer for contributors who didn’t list this information, WAMU used public records and internet databases to fill in the blanks. Connections between companies and their affiliates were made based on the addresses of the companies included, as well as documents such as legislative reports, court records and business registration files, and websites such as LinkedIn, OpenSecrets.org and Accurint. The reporters reached out to contractors ahead of publication to verify the affiliation of donors used in the database.

In addition, the reporters needed to connect corporate owners to their family members as the data do not explicitly make that connection. Any questionable ties were excluded, leaving a conservative total for the number of family members contributing to any given D.C. official or candidate.

The list of campaign contributors includes suspected members of Jeffery Thompson’s fundraising network. This list is based on several years of reporting, as well as internet searches, court documents and public records. Thompson and his affiliated donors often give the same amount of money to the same candidates on the same day. Several of these contributors have pleaded guilty to serving as “conduits” or straw donors for Thompson; federal investigators have said the total list of “conduits” is as high as 75. At least 15 candidates have received illegal fundraising from Thompson.
