President Joe Biden ordered U.S. intelligence officials to “redouble” their efforts to investigate the origins of the COVID-19 pandemic, including any possibility the trail might lead to a Chinese laboratory..

The Biden administration is joining worldwide pressure for China to be more open about the outbreak, aiming to head off GOP complaints the president has not been tough enough as well as to use the opportunity to press China on alleged obstruction.

Biden on Wednesday asked U.S. intelligence agencies to report back within 90 days. He directed U.S. national laboratories to assist with the investigation and the intelligence community to prepare a list of specific queries for the Chinese government. He called on China to cooperate with international probes into the origins of the pandemic.

Republicans, including former President Donald Trump, have promoted the theory that the virus emerged from a laboratory accident rather than naturally through human contact with an infected animal in Wuhan, China.

Biden in a statement said the majority of the intelligence community had “coalesced” around those two scenarios but “do not believe there is sufficient information to assess one to be more likely than the other.” He revealed that two agencies lean toward the animal link and “one leans more toward” the lab theory, “each with low or moderate confidence.”

“The United States will also keep working with like-minded partners around the world to press China to participate in a full, transparent, evidence-based international investigation and to provide access to all relevant data and evidence,” said Biden.

His statement came after weeks of the administration endeavoring to avoid public discussion of the lab leak theory and privately suggesting it was farfetched.
