House Republicans on the Select Subcommittee on the Coronavirus Pandemic have subpoenaed one of the authors of a controversial paper on the origins of COVID that cast doubt on the lab leak theory.

The subcommittee, led by Ohio Republican Brad Wenstrup and tasked with investigating the origins of the COVID pandemic, has subpoenaed documents and communications from Dr. Kristian Anderson. Anderson was one of the scientists who helped to draft the “The Proximal Origin of SARS-CoV-2” paper that cast doubt on earlier theories that COVID may have escaped from a lab.

“We are following the breadcrumbs of a COVID-19 cover-up straight to the source. Dr. Kristian Andersen played a pivotal role in potentially suppressing the lab leak hypothesis, and Americans deserve to know why this happened, who was involved, and how we can prevent the intentional suppression of scientific discourse during a future pandemic,” Wenstrup said in a statement.
