WASHINGTON – President Joe Biden announced on Wednesday that he had ordered a closer scrutiny of the intelligence services of the two equally plausible scenarios for the emergence of the Covid-19 pandemic.

Biden announced that earlier this year he hired the intelligence services to “prepare a report on their most recent analysis of the origins of Covid-19, including whether it was from human contact with an infected animal or from a laboratory accident . “”

“To date, the US intelligence community has partnered around two likely scenarios, but has not reached a definitive conclusion on the issue,” Biden said in a statement.

“Here is their current position: ‘while two elements in the IC are leaning towards the [human contact] Scenario and you lean more towards the [lab leak scenario] – each with low or moderate confidence – the majority of the elements do not believe there is enough information to assess whether one is more likely than the other, “said Biden.

Biden’s statement reflects the unique way the intelligence services present their findings to seated presidents. This includes explaining when various agencies within the community disagree and using a low to medium to high scale to quantify the level of confidence analysts have in the accuracy of their ratings.

“I have now asked the intelligence services to redouble their efforts to gather and analyze information that could bring us closer to a final conclusion and to report back to me in 90 days,” said Biden.

White House deputy press secretary Karine Jean-Pierre would not commit to making the results of any future report public.

Biden issued this new policy as the causes of the officially unknown coronavirus pandemic are under scrutiny.

The hypothesis that the virus might have escaped from a Chinese laboratory, although originally dismissed by some as a conspiracy theory, has gained more support in recent months.

The director of the Center for Disease Control and Prevention, Dr. Rochelle Walensky recently said on the Senate Testimony that an origin of a laboratory leak was “certainly” “a possibility.”

The CDC website currently states that while the exact source of the outbreak is unknown, “we do know that it originally came from an animal, likely a bat”.

In response, the Chinese embassy in the United States issued a statement on Thursday. Without naming a country, a spokesman said, “Some people have played the old prank of political hype on tracing COVID-19 in the world.”

“Since the COVID-19 outbreak last year, some political forces have been fixated on political manipulation and blame,” the statement said.

Covid-19 was discovered near the city of Wuhan in the Chinese province of Hubei. The Wuhan Institute of Virology, which has historically studied coronaviruses, is at the center of the turmoil over the origins of the deadly pandemic that killed nearly 3.5 million people.

Investigation of that lab intensified this week when the Wall Street Journal reported that three researchers there developed Covid-like symptoms in November 2019, just before the first cases of the virus were reported. The newspaper quoted a previously unpublished US intelligence report.

This latest news didn’t affect Biden’s decision to order an additional 90-day review, Jean-Pierre said on Wednesday.

“Nothing has changed,” she told reporters at the daily press conference. “This is just a continuation of what the president has been focusing on.”

So far, US efforts to determine the true origin of the pandemic have met opposition from the Chinese government, which restricted outside access to the Wuhan laboratory and refused to share a log of the scientists’ activities.

White House officials say China has not been “fully transparent” in its global investigation into the source of Covid-19 and that a full investigation is needed to determine if the virus originated in nature or from a laboratory.

“We have to get to the bottom of whatever the answer,” Andy Slavitt, Senior Covid Advisor to the White House, said this week. “We need a completely transparent process from China, we need WHO to help on this matter, and we don’t feel like we have it now.”

The possibility that the Covid pandemic started with a laboratory leak has been rejected by the WHO, which said in a March report that it was “extremely unlikely” that the virus was transmitted to humans in this way.

However, this report has been heavily criticized by scientists who said WHO briefly cut the chance of a laboratory accident compared to a natural-origin scenario.

“The report lacks critical data, information and access. It presents a partial and incomplete picture,” White House press secretary Jen Psaki said at the time when asked about the WHO’s stance on Covid’s origins.

The office of the director of the National Intelligence Service, who runs the country’s 18 intelligence agencies, did not respond to CNBC’s request for comment on Wednesday.
