Amazon CEO Jeff Bezos is placing the blame on President Donald Trump for Amazon's loss of a $20 billion cloud contract from the Pentagon - that went to its rival, Microsoft.

In a complaint filed Monday, Amazon said Trump's bias played a role in the decision and that the U.S. President launched repeated attacks in public and behind-the-scenes to steer the Pentagon contract, known as JEDI, away from Amazon Web Services.

The company claims Trump's motive was to "harm his perceived political enemy," Jeff Bezos, who is also the owner of the Washington Post.

The president has not been quiet about his dislike of Bezos and Amazon, repeatedly launching attacks against both.

As a result, the company claims the scrutiny made it impossible for the Pentagon to judge a winner fairly.

Amazon is now calling on the Pentagon to reevaluate the proposals that were submitted and issue a new award.
