The first six months of President Trump’s second term have been characterized by destruction of democratic processes, divisive and vindictive actions, and chaos in federal government agencies.
Since the Inauguration, the administration has systematically destroyed federal scientific systems. The Trump administration’s actions are not normal. This is an illegal power grab—a wholesale attack on the democratic systems upon which this nation was built.
Between January 20 and June 30 of this year, we documented 402 attacks on science. We define “attacks on science” as actions, statements, or decisions that originate from an elected official or political appointee in a federal agency that results in the censoring, manipulation, forging, or misinforming on scientific data, results, or conclusions conducted within the government or with federal funds.
When science is sidelined, people are harmed. In this report, we document the ways this administration has targeted the public science that we all depend on, and offer recommendations and resources to counter these attacks and hold the administration accountable.
