Boeing gave heavily to the Clinton Foundation after Hillary Clinton helped it secure a major deal with a Russian airline in 2009, author Pete Schweizer noted in his book, Clinton Cash.

The company was also involved in funding one of Clinton's pet projects at the State Department after the agency reportedly brushed aside ethical guidelines to secure a $2 million contribution.

Schweizer notes a $900,000 donation from Boeing to the Clinton Foundation came on the heels of a multibillion dollar contract between the Russian government and the aerospace behemoth.

Clinton pushed for the $3.7 billion deal in Russia as part of a policy she had dubbed "economic statecraft" in which she "would use her diplomatic leverage to help American companies be more competitive overseas," Schweizer wrote.

Flanked by Russian Foreign Minister Sergey Lavrov during an October 2009 speech from a Boeing plant in Moscow, Clinton thanked the Export-Import Bank for its role in supporting such deals.

"We're delighted that a new Russian airline, Rosavia, is actively considering the acquisition of Boeing Aircraft. And this is a shameless pitch for Rosavia – I've said what you wanted me to say, Sergey – to buy Boeing Aircraft. Right?" Clinton said during the speech. "The Ex-Im Bank would welcome an application for financing from Rosavia to support its purchase of Boeing Aircraft, and I hope that on a future visit I'll see a lot of new Rosavia-Boeing planes when I land in Moscow."

Rosavia was to be a state-owned airline holding company. When the deal for the Boeing planes was struck in June 2010, it was to provide aircraft to Russian carrier Aeroflot.

Russian President Vladimir Putin reportedly pushed back on the decision to build a Russian fleet with American planes. But Boeing and Airbus still supplied the majority of its aircraft through the agreement Clinton touted during her swing through Russia.

Boeing remains a major partner of the Clinton Foundation, supporting Clinton Global Initiative projects and donating between $1 million and $5 million to the charity.

The company also gave $2 million to support the State Department's efforts to host a pavilion at the 2010 World's Fair in China, an event that became highly politicized given the "pivot to Asia" policy Obama's State Department was to pursue.

Boeing's contribution to the pavilion, which was reportedly a priority project for Clinton, came one month after the secretary of state lobbied Russian leaders for the eventual contract with Aeroflot, the Washington Post reported.

In announcing the $2 million gift, "Clinton did not point out that, to secure the donation, the State Department had set aside ethics guidelines that first prohibited solicitations of Boeing and then later permitted only a $1 million gift from the company," the Post reported in April of last year. "Boeing had been included on a list of firms to be avoided because of its frequent reliance on the government for help negotiating overseas business and concern that a donation could be seen as an attempt to curry favor with U.S. officials."

The State Department's pavilion was sponsored by Pepsi, General Electric, Procter and Gamble, Pfizer, Intel, Honeywell, Yum! Foods, Boeing and Qualcomm.

Each of those companies have also donated heavily to the Clinton Foundation.

The fundraising effort within the State Department was led by Kris Balderston and Elizabeth Bagley, two longtime Clinton loyalists who enjoyed high-level appointments at the agency.

Balderston's government emails are the subject of a Freedom of Information Act lawsuit seeking records of his contact with the head of a consulting firm, Teneo Strategies, that often had its hand in Clinton business.
