WASHINGTON — Because the Protection Division prepares to solicit bids for cloud-computing work that might yield billions of {dollars} for Amazon, members of Congress are elevating new questions in regards to the firm’s efforts to win a $10 billion contract in the course of the Trump administration.

Beforehand unreleased emails present that Pentagon officers in 2017 and 2018 lavished reward on a number of of the tech executives whose corporations expressed curiosity within the authentic contract, particularly Amazon, whereas issues in regards to the firm’s entry seem to have been glossed over, in accordance with the emails, different paperwork and interviews.

Two Republican lawmakers who’ve pushed to rein within the dominance of Amazon and different tech corporations in shopper markets are seizing on the emails as proof that Amazon unfairly used its affect in competing for taxpayer-funded contracts.

Consultant Ken Buck of Colorado and Senator Mike Lee of Utah known as for Amazon to testify underneath oath about “whether or not it tried to improperly affect the biggest federal contract in historical past,” the $10 billion mission known as the Joint Enterprise Protection Infrastructure, or JEDI, that may transfer the Pentagon’s laptop networks into the cloud. Amazon didn’t reply to requests for remark.

No matter clout Amazon had within the Trump-era Pentagon had restricted impact. And the corporate additionally had a really high-level antagonist: President Donald J. Trump, who whereas in workplace regularly assailed Amazon’s chief executive on the time, Jeff Bezos, the proprietor of The Washington Put up. Amazon finally misplaced the JEDI contract, which was awarded to Microsoft in 2019, igniting questions on whether or not Mr. Trump’s hostility to Amazon performed a job within the consequence.

However, in a victory for Amazon, the contract was canceled by the Pentagon this month amid a contentious authorized battle over the award amongst Amazon, Microsoft and different tech corporations. The Protection Division instantly introduced that it was beginning a revised cloud program that might yield contracts for Amazon, Microsoft and presumably different companies, setting off what is anticipated to be an intense lobbying combat.

The newly launched emails and interviews with folks acquainted present a glimpse into the evolving relationship between the Protection Division and the large expertise corporations at a time when the Pentagon is more and more shifting its focus from planes, tanks and different {hardware} to software program and initiatives involving synthetic intelligence and machine studying.

They present how within the months main as much as the JEDI combat, high Pentagon officers and Silicon Valley executives engaged in an admiring courtship that led to high-level entry for a few of the companies that may later specific curiosity within the contract. The tech executives used the entry to induce Jim Mattis, Mr. Trump’s first protection secretary, to undertake cloud-based expertise and, in no less than one case, to advertise their very own firm’s expertise.

Throughout a visit to the West Coast in the summertime of 2017 to satisfy with executives from Apple, Amazon and Google, Mr. Mattis grew uncomfortable when he was subjected to an indication of Amazon’s cloud-computing merchandise on the firm’s Seattle headquarters throughout what he anticipated could be a extra basic dialogue of cloud expertise, in accordance with paperwork and a former senior Pentagon official who’s aware of the assembly.

The previous official mentioned the demonstration was attended by Mr. Bezos, with whom Mr. Mattis had simply met one on one, and quite a few his lieutenants, and was led by an govt in command of promoting merchandise from Amazon Net Providers, or AWS, to governments.

Briefing supplies ready for Mr. Mattis earlier than the assembly said that “it won’t be a gross sales pitch,” with “not” underlined for emphasis.

However instantly after the assembly, an aide to Mr. Mattis wrote in an e mail to a different Pentagon official that the session “appeared to morph into an AWS gross sales pitch.” Mr. Mattis “was good and gracious however I didn’t get an excellent vibe out of it,” the aide wrote, including that the one-on-one session previous the demonstration with Mr. Bezos “appeared to go very nicely” and that the Amazon founder and the protection secretary “did appear to click on on a private stage.”

The competitors for the JEDI contract shortly grew to become slowed down in bitter squabbling. IBM protested the request for proposal, suggesting it favored Amazon, whereas Oracle alleged that Pentagon officers had conflicts of curiosity associated to Amazon. When the contract went to Microsoft as an alternative, Amazon sued to dam it, arguing the Trump administration had interfered within the contracting course of due to Mr. Trump’s enmity towards Mr. Bezos.

An investigation by the Protection Division’s inspector basic dismissed probably the most critical allegations about Amazon and Pentagon officers improperly tilting the contracting course of to the corporate.

In a report final 12 months, the inspector basic concluded that the result of the JEDI contract was not affected by both Mr. Trump’s assaults on Amazon or the connections between the corporate and the Protection Division.

However the report omitted the expressions of concern in regards to the “gross sales pitch” demonstration for Mr. Mattis at Amazon headquarters, in addition to language from an e mail change wherein a Pentagon official informed two shut advisers to Mr. Mattis that the protection secretary’s chief of employees “defers” to them about whether or not to just accept a request from Amazon for a gathering on the Pentagon between Mr. Bezos and Mr. Mattis.

One of many shut advisers, Sally Donnelly, responded that Mr. Bezos “is the genius of our age, so why not.” Ms. Donnelly had labored within the Protection Division in the course of the Obama administration earlier than beginning a consulting agency in 2012 the place her purchasers included Amazon. That assembly doesn’t seem to have taken place, and Ms. Donnelly later testified to the inspector basic that she was being “flippant” and that Mr. Mattis’s chief of employees — not Ms. Donnelly — determined which conferences to take.

However lower than two days after her e mail calling Mr. Bezos a genius, Ms. Donnelly adopted up with an inventory of seven causes Mr. Mattis ought to meet with him. It included that Amazon had employed “many” former U.S. authorities intelligence specialists, that its cloud safety “was so convincing” to the C.I.A. “that the company two years in the past took the stunning step of migrating the majority of its safe work to Amazon,” and that Mr. Bezos’s possession of The Washington Put up gave him “affect past the enterprise world.”

The inspector basic’s workplace didn’t reply questions in regards to the omissions of particular traces from the emails, or whether or not these omissions left an incomplete image of the interactions between the Pentagon and Amazon.

“Our JEDI Cloud Procurement report speaks for itself — we stand by our findings and conclusions,” Dwrena Okay. Allen, a spokeswoman for the inspector basic, mentioned in a press release.

Michael N. Levy, a lawyer for Ms. Donnelly, mentioned in a press release that she “at all times adhered to all moral and authorized obligations and acted in one of the best curiosity of the nationwide safety of america.”

Her efforts to dealer conferences for Mr. Mattis and different tech executives had been “a part of the Division of Protection’s essential efforts to rework within the digital age,” Mr. Levy mentioned.

The emails — which date from 2017 and 2018 — had been launched by the Protection Division’s inspector basic in response to a Freedom of Data Act lawsuit introduced by a former inspector basic. The occasions described in them predate the formal Pentagon request for bids on the JEDI contract.

The emails present Mr. Mattis’s aides additionally lavishing reward on the chief executives of different corporations.

Ms. Donnelly known as Satya Nadella, the chief govt of Microsoft, “one of many sector’s ‘thought leaders’ and one of many nation’s most distinguished Indian Individuals,” and indicated it was vital for Mr. Mattis to satisfy with Mr. Nadella to reveal impartiality.

One other aide, whose identify is redacted within the emails, wrote that Milo Medin, a Google govt with whom Mr. Mattis met throughout his 2017 journey to the West Coast, was “nice.”

Mr. Mattis’s assembly with Tim Cook dinner of Apple was “additionally strong,” the aide wrote, noting that the 2 males “appeared to click on personally, Cook dinner mentioned he’s keen to assist nevertheless he can (and appeared to imply it).” The aide concluded that “one constructive observe of the journey is that everybody” on the numerous corporations “appeared to convey a honest ‘patriotic’ tune. I feel that may have stunned the Boss a bit.”

A month after the journey, the Pentagon issued a memo titled “Accelerating Enterprise Cloud Adoption.”

Mr. Buck, who labored on a bipartisan package of bills that handed the Judiciary Committee final month meant to weaken the dominance of Large Tech, joined with Mr. Lee in sending a letter to Mr. Bezos in May suggesting that Amazon tried “to monopolize a number of markets regarding authorities and/or business cloud computing providers by improperly influencing the Joint Enterprise Protection Infrastructure procurement course of.”

They called on the Justice Department to analyze whether or not Amazon “could have violated federal battle of curiosity and antitrust legal guidelines.” And so they accused the Defense Department’s inspector general of glossing over improprieties associated to Amazon’s bid for the JEDI contract.
