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 provided the intelligence rating based on the unique style with which he presented information to a seated president. This includes explaining when various agencies within the community disagree and using a low to medium to high scale to measure the level of confidence they have in the accuracy of their rating.

Biden issued the new guidelines as the causes of the still officially unknown coronavirus pandemic are increasingly being investigated.

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 is “certain” “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”.

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 The newspaper quoted a previously unpublished US intelligence report.

White House officials told reporters Tuesday that China had not been “completely transparent” in its global investigation into the origins of Covid-19 and that a full investigation was needed to determine whether the virus came from 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, told reporters on Tuesday. “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 World Health Organization said in March it was “extremely unlikely” that the virus was transmitted to humans through an accidental laboratory leak. 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.
