New York (CNN) As Covid-19 vaccine-related misinformation continues to spread on Facebook, one of the platform's former executives is calling for the company to focus on transparency. President Joe Biden recently said platforms like Facebook are "killing people" with vaccine misinformation. After more than 11 years working at Facebook, "It's one of the main reasons that I quit," he said. The White House is focusing on turning up the heat on the so-called Covid "disinformation dozen" who are using social media to spread false or misleading claims about the vaccines. "There's about 12 people who are producing 65% of anti-vaccine misinformation on social media platforms," White House Press Secretary Jen Psaki said Thursday.
