“We could not definitively determine the full extent or nature of interactions that administration officials had, or may have had, with senior DoD officials regarding the JEDI Cloud procurement because of the assertion of a ‘presidential communications privilege,’” the report said.

Last fall, the Department of Defense awarded the $10 billion contract to Microsoft and tasked the company with replacing its legacy cloud-computing systems. Amazon quickly challenged the decision. It filed a complaint with the US Court of Federal Claims and followed that with a lawsuit, in which the company said President Trump “used his power to ‘screw Amazon’ out of the JEDI Contract as part of his highly public personal vendetta against Mr. Bezos, Amazon, and the Washington Post.” A spokesperson said the “evaluation process contained clear deficiencies, errors, and unmistakable bias.”

In February, a judge granted Amazon’s request to put the Microsoft contract on hold. The inspector general report released today may clear the way for Microsoft to continue -- or it might not. According to a past report by CNBC, Amazon hopes to depose President Trump and six other officials as part of its lawsuit. It’s unclear whether the inspector general’s report will change that.
