Former U.S. Director of National Intelligence John Ratcliffe is set to testify to the House Select Subcommittee on the Coronavirus Pandemic that "a lab leak is the only explanation" for the initial outbreak of the COVID-19 virus. Ratcliffe served under former President Donald Trump from May 26, 2020, to January 20, 2021.

His prepared testimony says "the intelligence community's sources for the information are numerous, diverse, and unassailable," Fox News reports.

"My informed assessment, as a person with as much or more access than anyone to our government's intelligence during the initial year of the virus outbreak and pandemic onset, has been and continues to be that a lab leak is the only explanation credibly supported by our intelligence, by science and by common sense," the prepared testimony reads.

According to the testimony document, Ratcliffe is set to criticize scientists, members of the press, and social media companies for dismissing the lab leak theory as a debunked "conspiracy theory." The prepared testimony states "national and electoral politics were also influencing" the intelligence community's "analysis of [its] intelligence on China."

"To this day, the CIA, unquestionably the world's premier spy agency with an unrivaled capacity to acquire information and near limitless resources to do so, has continued to state that it does not have enough information to make any formal assessment," the prepared testimony reads. "To put it bluntly, this is unjustifiable — and a reflection not that the agency can't make an assessment with any confidence, only that it won't."

"The real problem is, now three-and-a-half years later, the only plausible assessment the agency could make is that a virus which killed over a million Americans originated in a Chinese Communist Party-controlled lab whose research included work for the Chinese military. Such an assessment would have enormous geopolitical implications that the Biden administration seemingly does not want to face head-on."
