AI Verified Relevant: in context, this quote is Dr. Venter's criticism of intelligence reports reviewed for the lab-leak hypothesis; the same source says zoonotic origin is the best-supported hypothesis and that the intelligence reports were speculative and not science-backed. That makes a stance on the lab-incident-vs-zoonotic-spillover statement determinable.

AI Verified The quote dismisses intelligence cited for a lab-origin theory as "very speculative" and "not backed up by science." In the article’s context, Venter/SAGO say zoonotic spillover is the "best supported hypothesis" while the lab-leak idea could not be confirmed or excluded because key data are missing. That makes the author more likely opposed to the claim that COVID-19 originated from a lab-related incident rather than natural spillover. · YouCongress gpt-5.4-2026-03-05 · 3mo ago

AI Verified Verified: the Health Policy Watch article dated 27/06/2025 contains the exact sentence and attributes it to Marietjie Venter (“Venter added”). WHO’s 27 June 2025 materials also identify Venter as SAGO chair presenting the report that day, and the SAGO report says the reviewed intelligence reports included speculative assertions and potential political bias, consistent with the quote.
