A Yosemite National Park wildlife biologist and ranger, Shannon Joslin, who identifies as nonbinary and is a graduate student at UC Davis, was fired after hanging a transgender pride flag from El Capitan in May 2025. The act was a protest against the policies of the Trump administration. In addition to Joslin's dismissal, some park visitors who participated in the demonstration may face potential prosecution due to tightened protest restrictions implemented under President Donald Trump. The National Park Service took action against Joslin for the unauthorized display, which sparked widespread attention and debate about free speech and protest rights within national parks.
