A movement by scientists to march on Washington as a protest against the Trump White House’s treatment of science has gained traction, with more than 115,000 supporters joining a Facebook group for the cause.

The move follows a slew of measures from President Donald Trump that scientists and policymakers have said could undermine science and its role in society. “It is time for scientists, science enthusiasts, and concerned citizens to come together to make ourselves heard!” organizers wrote on the page.

“I can be here every weekend,” she said before the march.
