Since taking office in January, some people have felt President Trump has been a bit hostile to the science community. His administration has put policies in place that silence federal agencies from publicly discussing climate change and has proposed massive budget cuts to the National Institute of Health, the Environmental Protection Agency, the National Oceanic and Atmospheric Administration, and the Department of Energy.
