McCaul, the top Republican on the House Foreign Affairs Committee, described Biden’s investigation as “long overdue” on CNN’s State of the Union, but warned that it may not be conclusive because “it destroys everything in the laboratory to have”.
McCaul cited repeated examples of China’s efforts to block information about Covid-19 as the reason for the punishment, and said the U.S. should stop buying certain key products from China.
“My answer to this whole thing is the supply chain,” said McCaul. “We have to pull our supply chain out of the region, ie medical care, rare earth mineral supply.”
McCaul and Senator John Cornyn (R-Texas) proposed a bill, the CHIPS for America Act, to support the manufacture of US semiconductors.
“If we can pull these chains out of China, it will be economically damaging,” said McCaul. “And that would be very punitive by nature.”
Biden administration officials had previously said that investigations into the origins of Covid-19 should be led by an independent group like the World Health Organization, but WHO’s initial efforts have been hampered because China would not share important laboratory records and data.
The Senate also unanimously passed a measure by Senator Joni Ernst (R-Iowa) that would prohibit US funding of the Wuhan Institute of Virology.
Matthew Pottinger, former deputy national security advisor to President Donald Trump, said it was important to get answers on the causes of the pandemic.
“It could have emerged from a laboratory. It could have emerged from nature,” he said on NBC’s Meet the Press. “Both are valid, neither is backed by concrete evidence, but there is increasing circumstantial evidence specifically supporting the idea that this may have leaked out of the laboratory.”
