The only benefit to prolonging it IMO is to come up with a more convincing lie.
But here's the Thing.
The FDA has had 5 Years to come up with Lies to Questions about deeming. And had to have Known that there was a strong Likelihood that Sen Johnson would submit questions to them.
So the Plan from the Start was to Blow Off an Oversight Committee? And then force the Sen. Johnson's hand to Subpoena the HSS and FDA?
