White House national security adviser Jake Sullivan says there is "not a definitive answer" on whether the COVID-19 pandemic developed from a lab leak in Wuhan, China.

“If we gain any further insight or information, we will share it with Congress, and we will share it with the American people," Sullivan said on CNN’s State of the Union. "But right now, there is not a definitive answer that has emerged from the intelligence community on this question."

CORONAVIRUS MOST LIKELY ORIGINATED FROM A LAB LEAK, US DEPARTMENT CONCLUDES

Sullivan's comments come after the Wall Street Journal reported that the Department of Energy concluded the lab leak theory is the most plausible explanation for the pandemic that swept into the United States and caused nationwide shutdowns in 2020.

The report stated that four other agencies believe that COVID-19 stemmed from natural transmission, while two other agencies, including the CIA, have not reached a full conclusion. The Energy Department joins the FBI in its conclusion.

However, Sullivan pointed to the department's "low confidence" conclusion and said President Joe Biden has directed the intelligence community repeatedly to use resources to get "to the bottom of this question."

Previously, the Energy Department was undecided in its theories but changed its perspective in light of new intelligence. Specifics have not yet been revealed, but all agencies seem to agree that COVID-19 was not the result of a Chinese biological weapons program.

Sullivan said there are a “variety of views” on the origin of COVID-19, but right now, agencies “just don’t have enough information to be sure.”
