It happened in Canada
This suppression of science in support of ideological goals - in particular climate change - happened during the Harper administration in Canada 2006 - 2015. If science disagrees with your ideology, get rid of the science.
Unfortunately, we did not have twitter back then to the degree we do now, so the scientists had no venue to report on what was happening.
It was a bleak 10 years for science in Canada.
Trump will find ways to clamp down on all dissent - it can happen in the US.
Good thing the way back machine is mirroring outside the US.
