The Trump administration has earned criticism for its stances on energy and the environment. The Environmental Protection Agency dismissed various scientists from its advisory board earlier this month, prompting two other board members to resign in protest.

Trump's Interior Department froze the work of over 200 members of its advisory boards, committees and subcommittees, a third of which cover science-related issues.

Trump claimed in 2012 that climate change is a “Chinese hoax.” In April, thousands of people gathered in D.C. for two marches criticizing Trump's stances on science and climate change.
