Bernie Sanders Ad Attacks Amazon's Climate Change Policies.
The 2020 presidential candidate has been a frequent critic of the e-commerce giant.
The new video features two employees, Emily Cunningham and Maren Costa.
The women have made headlines for publicly speaking out against Amazon's climate change guidelines.
They also claim that Amazon threatened to fire them after they spoke to the press about the issue.
Amazon's workers are speaking out to say: Jeff Bezos should not be in the business of fossil fuel extraction. The company’s response? Retaliate with threats of firing. I stand with these employees who are fighting to protect the only home we have.
Cunningham and Costa both belong to advocacy group Amazon Employees for Climate Justice.
The group, along with Sanders in the ad, have pushed for the company to leave the fossil fuel industry behind.
Last year, Amazon released new goals that will make it more climate-friendly.
