HHS has a link to terminated grants and contracts. This is an interactive viewer of this PDF. For NIH grants and contracts, additional details have been added from NIH RePORTER.
Note that some of the facets for filtering rely on RePORTER data. For example, the "Organization State" facet only includes records for NIH grants and contracts that are in NIH RePORTER.
Methodology and code for the viewer can be found here. Please leave a comment if you encounter any issues or mistakes.
