List of current members of the United States Congress by wealth
This list of members of the United States Congress by wealth includes only the forty richest current members of Congress and displays the difference between assets and liabilities for the member and his or her immediate family, such as a spouse or dependent children. These figures can never be entirely accurate, because the financial disclosure requirements for the United States Congress are approximate by design. The original documents for each member's disclosure are publicly available on a database website, maintained by the Center for Responsive Politics. For 2018, the median net worth of members of Congress was $511,000.
