In a redacted filing released today by the US Federal Court of Claims, attorneys for Amazon asserted that Amazon Web Service's loss of the Department of Defense Joint Enterprise Defense Infrastructure (JEDI) cloud computing contract to Microsoft's Azure was the result of "improper pressure from President Donald J. Trump, who launched repeated public and behind-the-scenes attacks to steer the JEDI Contract away from AWS to harm his perceived political enemy—Jeffrey P. Bezos, founder and CEO of AWS' parent company, Amazon.com, Inc. ("Amazon"), and owner of the Washington Post."

The suit cites Trump's instructions to former Secretary of Defense James Mattis to "screw Amazon" out of the contract, as recounted by Mattis' former chief speechwriter, and numerous other incidents of direct interference by Trump in the contract competition, including ordering an "independent" review of the contract by Defense Secretary Mark Esper in August of 2019.
