Legislative Affair's (LA) mission is to act as the principal interface between the ODNI (and the IC on certain issues) and Congress. Its charge is to facilitate the implementation of those sections of the National Security Act of 1947, as amended, which stipulate that the heads of the IC agencies shall keep the Congressional intelligence committees fully and currently informed of all intelligence activities of the United States. This is accomplished through hearings, budget documentation, briefings, Congressional Notifications, written reports, site visits, correspondence, phone calls, and emails.

LA provides support and legislative strategies to senior ODNI leadership; leads Congressional engagements on behalf of the ODNI; obtains Congressional support for ODNI/IC budget requests and authorities/policies; and in coordination with the Office of the General Counsel provides IC views and support to the White House and National Security Council Staff on legislative matters.
