Sen. Rand Paul, R-Ky., has released another batch of documents related to the COVID-19 pandemic. The latest records show that U.S. officials intercepted undeclared biological materials tied to a U.S.–China coronavirus research network as early as 2018, likely in an attempt to avoid international tensions and regulatory scrutiny, Paul said. The documents, which include a Department of Homeland Security intelligence report, primarily focus on a network centered around University of Minnesota virologist Fang Li. CBP reported that the vials likely contained a species of fly commonly used as a model organism in biological research. As Chairman of the Senate Homeland Security and Governmental Affairs Committee, Paul has released several batches of internal documents through his public archive, "The Reading Room."
