Laid-off employees who hung a U.S. flag upside-down at Yosemite National Park say the action was a call to protect the nation's public lands.

A group of workers at California's Yosemite National Park positioned the U.S. flag on Saturday near the Horsetail Fall​ where crowds gather to witness Yosemite's annual firefall​.

The flag was reportedly hung over the side of El Capitan as a sign of protest by Yosemite employees concerned about the recent downsizing carried out as part of the Trump administration’s cost-cutting initiatives.
