Fact check
AI analysis“The US government wants to spend $30.3 million over the next five years on an improved form of lie detector, according to a Department of Defense budget request.”
Reasoning
The FY2025 President's Budget Request and supporting CRS analysis both list a $30.3 million line item for an advanced polygraph/AI lie‑detection program, matching the claim that the government wants to spend that amount. Contradictory sources refer to actual appropriations, not the request itself, and therefore do not refute the claim.
On confidence: Multiple primary and independent sources directly cite the DoD budget request for $30.3 million over five years for an AI‑enabled lie detector.
Important context
The figure reflects a proposed budget request, not an enacted appropriation. Congressional appropriations may allocate less (or zero), as indicated by later reports.

Limitations
Verification depends on the accuracy of the cited budget documents; if the documents are revised or misinterpreted, the conclusion could change. The claim does not address whether the funds will ultimately be approved or spent.
