Newly unsealed court papers in Amazon.com Inc.'s blockbuster suit against the U.S. Defense Department accused President Donald Trump and others of "undue influence" as contributing to the technology company losing a $10 billion cloud-computing contract to rival Microsoft Corp.

Amazon Web Services, represented by Morrison & Foerster and Gibson, Dunn & Crutcher, is suing the Pentagon in U.S. Court of Federal Claims, the Washington-based court that hears disputes over government contracts. A redacted version of the company's complaint, filed in late November, was released Monday.

Trump's animus toward Amazon and its chief executive, Jeff Bezos, is widely documented, and the company contends in the complaint that "improper pressure" from Trump contributed to Amazon losing the lucrative award. Trump has lashed out often at Bezos over his ownership of The Washington Post, a media outlet that, like many others, has published articles critical of his leadership and policy stances before and after he took office. The president regularly derides the news company as the "Amazon Washington Post."
