Dr. Fauci literally created a bioengineered weapon in a lab, designed to kill half of the population.

The claim that Dr. Fauci literally created a bioengineered weapon designed to kill half the population is false because multiple reliable sources and official investigations show no evidence that he funded or created such a weapon or that COVID-19 was engineered as a bioweapon.

The reporting

What the Evidence Shows

Extensive investigations and reporting from reputable news organizations and fact-checkers have found no credible evidence supporting the claim that Dr. Anthony Fauci created or funded a bioengineered weapon intended to kill half the population. Official reviews, including federal inquiries, have been inconclusive about the exact origin of COVID-19 but have not confirmed it was engineered or deliberately released as a bioweapon.

Dr. Fauci himself has repeatedly denied funding gain-of-function research linked to the creation of the virus. While some political figures and commentators have accused him of funding risky research or hiding information, these claims lack substantiation from primary evidence. Some sources allege funding of techniques related to virus research, but these do not equate to creating a weapon designed for mass killing.

The lab leak theory remains debated, but it does not imply intentional weaponization by Dr. Fauci. Overall, the claim is a conspiracy theory unsupported by credible evidence.
