White House officials pressured Amazon in 2021 to censor and minimize access to books on its online site that questioned the safety or efficacy of vaccines, according to e-mails released earlier this month by House Judiciary Committee Chairman, U.S. Representative Jim Jordan of Ohio.

The campaign to curtail any vaccine-related book sales during the height of the pandemic was led by President Biden’s Senior Advisor for Covid-19 Response, Andrew Slavitt, and sought to avoid the spread of “propaganda and misinformation.”

“Who can we talk to about the high levels of propaganda and misinformation and disinformation of [sic] Amazon?” Slavitt wrote to Amazon in a Mar. 2, 2021, e-mail.
