Amazon Web Services filed suit Friday in the U.S. Court of Federal Claims challenging the Pentagon’s decision to award the $10 billion JEDI cloud contract to Microsoft.

The basis of Amazon’s complaint isn’t clear at this time. Amazon has requested a protective order claiming that the “complaint and related filings contain source selection sensitive information, as well as AWS’s proprietary information, trade secrets, and confidential financial information, the public release of which would cause either party severe competitive harm.”

While it isn't clear what Amazon is alleging, what is known is Amazon's case will likely center around President Donald Trump and Department of Defense (DoD) CIO Dana Deasy, both of whom are cited in a notice describing several video clips submitted into evidence Friday.

Trump has been at the center of a highly public feud with Jeff Bezos, CEO of Amazon and owner of the Washington Post.

The clips submitted by Amazon reportedly depict Trump speaking at a campaign rally in Texas in February 2016 and at a press conference on July 2019. The notice also makes reference to a video of Deasy's confirmation testimony on Oct. 29 and a clip from Fox News on July 21.

Microsoft also filed a leave for intervention on Friday, entering the lawsuit on the basis that “the disposition of this matter will directly affect Microsoft’s interests in the awarded contract, which carries the potential for significant economic and other harms to Microsoft,” the filing reads.

The filing comes just weeks after the cloud giant announced its intent to protest the Joint Enterprise Defense Infrastructure, or JEDI, award. And in an email to SDxCentral, an AWS spokesperson suggested that the process for selecting the winner was biased and influenced by politics.

“AWS is uniquely experienced and qualified to provide the critical technology the U.S. military needs and remains committed to supporting the DoD’s modernization efforts,” the AWS spokesperson said. “We also believe it’s critical for our country that the government and its elected leaders administer procurements objectively and in a manner that is free from political influence. Numerous aspects of the JEDI evaluation process contained clear deficiencies, errors, and unmistakable bias — and it’s important that these matters be examined and rectified.”

The DoD awarded the contentious contract to Microsoft last month in a major upset for Amazon, which has long been seen as the front runner in the race for the 10-year $10 billion deal to move approximately 80% of all DoD data off premises and into a single cloud.

However, almost from the start, the process has been fraught with controversy. Amazon is the latest cloud provider to challenge the DoD decision. Oracle and IBM last year filed protests against JEDI. Oracle renewed its protests earlier this month officially filing an appeal claiming that the process was preferential to Amazon.

Bloomberg reports, Oracle is making the case that JEDI violated federal procurement law and was influenced by existing relationships between former Pentagon officials and Amazon.

This summer the Pentagon inspector general launched an investigation into potential “misconduct” related to the contract process.

“From the looks of it, the DoD process looked unstructured and was full of fits and starts … almost political,” wrote Patrick Moorhead, president and principal analyst at Moor Insights and Strategy, in an earlier email.
