Havana Syndrome: the congressional report that says the government’s own investigation was not honest

On December 5, 2024, House Permanent Select Committee on Intelligence CIA Subcommittee Chairman Rick Crawford released an unclassified interim report on the Committee’s investigation into Anomalous Health Incidents, the official government term for Havana Syndrome. The report followed 48 interviews of current and former personnel from the CIA, FBI, ODNI, DIA, and State Department.

As of January 2024, 334 American officials had qualified for AHI-related medical care through the military health system. Affected personnel include White House staff, CIA officers, FBI agents, and military officers, along with their families, some of whom describe the onset as a sudden, directional sound followed by lasting neurological symptoms.

The ODNI’s formal Intelligence Community Assessment, delivered in March 2023, concluded it was very unlikely that a foreign adversary or a novel weapon caused the reported incidents, attributing most cases instead to preexisting conditions, conventional illness, and environmental factors. The House Intelligence Committee’s December 2024 report does not merely disagree with that conclusion. It states the ODNI assessment lacked analytic integrity and was highly irregular in its formulation, and separately reports that a CIA Subcommittee found direct evidence the 2023 assessment was developed in a manner inconsistent with analytic integrity.

The Committee further states that the intelligence community actively attempted to impede its investigation. This is not outside criticism. It is one official body of the United States government formally accusing another of producing a misleading assessment and obstructing congressional oversight of it.

In January 2025, the National Security Council issued a statement indicating earlier judgments were under review. Then-Committee Chairman Mike Turner stated publicly that a foreign adversary is likely responsible. On November 12, 2024, senior National Security Council staff convened affected intelligence officers in the White House Situation Room, described by attendees as an unusual and extraordinary session given years of what those officers characterized as resistance from their own parent agencies.

This establishes that a congressional oversight committee formally found the government’s own official assessment of Havana Syndrome to be procedurally compromised, not merely wrong, and documented obstruction of its investigation by the intelligence community. This is confirmed in the Committee’s own released report, a public government document.

What this does not establish is what actually caused the reported symptoms in the 334 documented cases. The Committee’s report challenges the integrity of the process that produced the very unlikely finding. It does not, on its own, prove foreign involvement or identify a specific weapon or mechanism. Separate NIH-led clinical research published in 2024 found no consistent MRI-detectable brain injury across cases, a finding that exists alongside, and in tension with, the reported severity of symptoms described by affected personnel.
