Iran–Contra: locate the investigation records.
An archival finding aid helps reconstruct the documentary trail of an investigation.

Use the finding aid
The National Archives describes Lawrence Walsh’s Iran/Contra records. The description helps locate an investigation’s files rather than substituting for every underlying document. U.S. National Archives and Records Administration ↗
Separate records by role
Distinguish testimony, correspondence, investigative notes, reports, and legal findings. Record who produced each source and the question it can actually answer. U.S. National Archives and Records Administration ↗
Build a dated chain
For a specific transaction or decision, compare contemporaneous documents with later testimony. Uncertainty about one link should remain visible in the account. U.S. National Archives and Records Administration ↗
