While not an explicitly political protest, the March for Science, now in its second year, last year targeted the environmental policies of the Trump administration, including cuts to federal research grants and large-scale deregulation by the EPA.

The march, held in Washington, D.C., on Saturday with satellite events in various other cities, promoted a petition to "send a message to Congress and the White House that you support qualified scientific leadership."

Colorful signs again dominated the rallies this year. Some protesters wore lab coats and others held signs that read "Send a scientist to the state house" and "Science not Silence," an unofficial slogan of the protests.

One marcher's sign warned that "at the start of every disaster movie there's a scientist being ignored."
