A more thorough explanation:

The Office of Policy Development (OPD) is a part of the Executive Office of the President. It includes two councils: the Domestic Policy Council and the National Economic Council. The OPD was created in 1993 by Executive Order 12859.

The Domestic Policy Council focuses on developing policies related to issues within the United States, such as education, healthcare, and civil rights. The National Economic Council focuses on economic policies, such as taxes, trade, and job creation.

For example, the OPD may work on developing a policy to improve access to healthcare for low-income families. They may also work on a policy to increase job opportunities in a certain industry.

The OPD plays an important role in shaping the policies of the United States government. By bringing together experts from different fields, they can develop policies that address important issues facing the country.
