I would suggest contacting a congressperson who sits on a committee with oversight of the FDA. Your best bet on a response is if your own representative sits on one of these committees:
Senate Committee on Health, Education, Labor Pensions
House Committee on Energy and Commerce Subcommittee in Health
If your representative is not on either committee, you can try Chair Patty Murray’s office for the Senate or Chair Anna Eshoo for the House. The Committees themselves also have full time staff who can sometimes be found on LinkedIn.
It would be a good idea to ask them about whistleblower protection, especially if you cannot hire an attorney, which was a suggestion.
Making this suggestion for a few reasons: if it’s pervasive at the FDA, their Internal Affairs may be limited. Though damaging, this isn’t a crime so law enforcement isn’t appropriate. If contacting Congress goes nowhere, you could consider media, but their incentives will be attention, not necessarily resolution and definitely not your protection.
My impression of the George Mason academics is that they lean conservative.
Another conservative message I have seen among EAs is a general anti-tax sentiment. This has included practical advice on promotion of donor-advised funds, a personal asset that serves to reduce taxes. The argument seems to be that an EA can better direct what would have been taxes to a high impact charity than the government would be able to spend it.
