I expect that’s about not trusting the foreigners who did the clinical trials (I have heard this)[1], and not so much about expecting that Americans are biologically different from foreigners.
Specifically, someone with some knowledge told me that the FDA knows that there are some countries where the trials are completely untrustworthy. And that there was a political decision where they said, “If we disallow trials from some countries but not others, there will be much complaining and we’ll probably be called racists”, and solved the issue by disallowing trials from all foreign countries.
