Fact check
AI analysis“The US government wants to spend $30.3 million over the next five years on an improved lie detector, according to a Department of Defense budget request.”
Reasoning
The Department of Defense FY2025 budget request explicitly allocates $30.3 million over FY2025‑FY2029 for an improved lie‑detection system, matching the claim. Independent analyses and news articles confirm this request. Contradicting sources discuss later legislative actions that reduced or eliminated the funding, but they do not negate the existence of the original request.
On confidence: Strong primary source (DoD budget request) directly states the $30.3 million request, corroborated by independent CRS report and reputable news coverage.
Important context
The claim refers to the budget *request*, not the enacted appropriation. While the request sought $30.3 million, subsequent legislation and GAO findings indicate that the amount was later reduced or not funded.

Contradicting (2)
- Tier 1 — Primary sourceNational Defense Authorization Act for Fiscal Year 2025 (Public Law 118‑123)
