The National Institutes of Health (NIH), a part of the U.S. Department of Health and Human Services, is the nation’s medical research agency — making important discoveries that improve health and save lives. The NIH conducts its scientific research through the NIH Intramural Research Program (IRP) and provides significant biomedical research funding to non-NIH research facilities through its Extramural Research Program.

Understanding the Context

The National Institutes of Health (NIH) is the primary Federal agency for conducting and supporting medical research. The NIH has proven a difficult target for the White House budget director, because lawmakers have a symbiotic relationship with the agency. The NIH has obligated just $5.8 billion of its extramural funding in FY 2026, 15% of the estimated $38 billion the agency needs to spend by Sept. 30.
