Meanwhile, Trump says his administration values “rigorous science.”
Amid the Trump administration's plan to gut the Environmental Protection Agency, cut billions in scientific research, and eliminate science advisers' role in the government, thousands of people around the world participated in marches for science Saturday to defend the role of science and evidence-based policies.
The marches, which coincided with the annual Earth Day celebration, have sparked debate within the scientific community over whether scientists should be actively engaged in political actions. Organizers for the marches say the event is nonpartisan—there is no mention of Trump on its website—but assert silence is no longer an option amid the threats posed by Trump and many of his advisers.
Mother Jones has three reporters on the scene, Pema Levy in DC, Jaelynn Grisso in New York, and Karen Hao in Los Angeles. For up-to-the-minute news on the marches, be sure to follow them, along with our rolling collection of updates below:

12:48 pm ET Mother Jones reporter Pema Levy talks to scientists at the DC march:
Mike Khan is a microbiologist at Washington State University. He said scientists are looking at issues like global warming and realizing they need to speak out publicly about the problem. "Science says we are going in some awfully bad places, and a lot of politicians are not willing to accept that," he said. "I'm out here in the rain because I think that's a problem."
Dr. Laura Anderko studies the effects of mold, pesticides, lead, climate change, and other environmental hazards on children's health, but says her funding is threatened. "Everything that we've done to save humanity goes back to science: clean water, clean air, all of that," she said.
