Watch Hillary Clinton Make Surprise Appearance at Tribeca Film Festival

Former Secretary of State talks about efforts made to prevent elephant poaching at 'The Protectors' screening

Hillary Clinton made a surprise appearance at the Tribeca Film Festival Saturday to take part in a panel for a short film about elephant poaching.

Hillary Clinton made a surprise appearance at the Tribeca Film Festival Saturday to take part in a panel for The Protectors: Walk in the Ranger's Shoes, a Kathryn Bigelow-directed short film about elephant poaching.

The film, shot as a VR experience, documents a day in the life of a park ranger in the Democratic Republic of Congo that is tasked with saving elephants from the dangerous ivory trade.

"We've got to bust this market so it can't come back," Clinton said of elephant poaching, an illegal practice she fought both as Secretary as State as well as through her Clinton Global Initiative foundation, the Associated Press reports.

"I’m very proud that under President Obama, the United States passed a near federal ban on the transportation and interstate trafficking of ivory in our own country. The Obama administration had three overriding goals: Stop the killing, stop the trafficking, and stop the demand… And part of that is protecting these rangers."

Clinton also made note of the massive March of Science that took place nationwide on Saturday, Earth Day. "We are marching on behalf of science, and part of science is understanding the intricate relationships that we share with all those on this planet and particularly large mammals like elephants, who have a role to play both in reality and in our imaginations."

National Geographic will premiere The Protectors on May 1 on VR app Within, then on YouTube and Facebook360 the following week.
