What is the largest organization within the Executive Office of the President?

The Office of Management and Budget (OMB) is the largest organization within the Executive Office of the President. This is because the OMB plays a crucial role in the federal budget process, overseeing the allocation of government funds and ensuring that agencies operate within their budgetary limits. It also assesses the performance of federal programs, provides guidance to federal agencies, and prepares the President's budget proposal for Congress.

This significant responsibility makes the OMB larger in terms of staff and scope compared to other entities within the Executive Office. While the National Security Council focuses on security issues, the Council of Economic Advisors advises on economic policy, and the Office of National Drug Control Policy addresses substance abuse issues, none of these organizations encompass the same level of comprehensive oversight of the federal budget or management functions as the OMB. Hence, its prominence and size within the Executive Office of the President are well justified.
