Coburn’s financial disclosure forms

Each year, lawmakers are required to file financial disclosure forms that list assets, liabilities, stock transactions, outside employment, spousal employment and travel reimbursements.

Stock trades and overlapping interests

In 2007, Coburn placed a legislative hold on the Genetic Information Nondiscrimination Act, saying he wanted changes to address fears about exposing employers and insurance companies to lawsuits. Coburn reported buying bonds in a genetic technology company the day a compromise he sought was reached on the bill. Coburn then lifted the hold and voted for the bill.

Response by Coburn

Coburn said the Affymetrix purchases were made without his knowledge by his investment adviser. He said the timing was coincidental. His office said it has no record of any contact with Affymetrix.

About the data

The estimation of assets for lawmakers is based on calculating the midpoint of reported value ranges for holdings and liabilities that members of Congress list on financial disclosure forms. It does not reflect assets lawmakers are not required to disclose, such as personal residences and non-interest bearing bank accounts. The estimation is not intended to provide a complete portrait of the net worth of each legislator, but rather show their relative standing in Congress and how their holdings have changed over time.
