[Excerpt] Conflict of interest regulations and restrictions on certain private employment opportunities for a federal officer or employee do not necessarily end with the termination of the officer’s or employee’s federal service. This report is intended to provide a brief history and description of the provisions of federal law restricting employment opportunities and activities of federal employees after they leave the service of the executive or legislative branches of the federal government. The conflict of interest provisions applicable after one leaves government service to enter private employment are often referred to as “revolving door” laws.
