The practice of squelching government scientists by political appointees is commonplace now in this Administration. We've seen it with global warming, various EPA policies and now salmon issues in the west. I've run into it in Oregon, California and just a couple of weeks ago, in Florida (not about salmon, but other water issues).
Scientists are threatened with demotion, or reassignment to far less desirable posts if they're career employees, or dismissal if they're not. The amazing thing is, it's commonly known and accepted that this is happening and there is no outrage from the general public or the legislative branch. These scientists are working with public tax dollars on publicly supported projects and many times their work is smothered by political appointees with an agenda.
