Among the climbers who helped hang the transgender flag was Pattie Gonia, an environmentalist and drag queen who uses the performance art to raise awareness of conservation issues. For the past five years, Gonia has helped throw a Pride event in Yosemite for park employees.

The National Park Service confirmed Tuesday it is working with the Justice Department to pursue disciplinary action.

A trans park ranger was fired from Yosemite National Park last week after hanging a massive transgender pride flag in protest of the Trump administration.
