President Trump's "repeated public and behind-the-scenes attacks" against Amazon led the Pentagon to choose a lesser bid from Microsoft for a massive cloud computing contract that officials have labeled a crucial national security priority, Amazon alleged in a complaint made public Monday.

Amazon is suing the Pentagon over a $10 billion cloud-computing contract awarded to Microsoft. Amazon said it filed a legal complaint Friday with the US Court of Federal Claims seeking to challenge the decision.

The Pentagon awarded its controversial $10 billion cloud computing business to Microsoft Friday evening, spurning a bid from Amazon, which had been expected to win the contract. President Donald Trump had expressed opposition to giving the lucrative award to a company led by Jeff Bezos, a regular target of his ire.
