A new book titled, “Clinton Cash: The Untold Story of How and Why Foreign Governments and Businesses Helped Make Bill and Hillary Rich,” by Peter Schweizer, will be released on May 5, and is expected to provide insight into the influence of foreign donors to the Clinton Foundation had on US foreign policy during Hillary Clinton’s tenure as Secretary of State.

After obtaining a copy, the New York Times hailed the book, which “asserts that foreign entities who made payments to the Clinton Foundation and to Mr. Clinton through high speaking fees received favors from Mrs. Clinton’s State Department in return” as the “most anticipated and feared book of a presidential cycle still in its infancy.”

Peter Schweizer, a conservative author and the President of the Government Accountability Institute, has written books such as Architects of Ruin: How a Gang of Radical Activists and Liberal Politicians Destroyed Trillions of Dollars in Wealth in the Pursuit of Social Justice (2009), Throw Them All Out: How Politicians and Their Friends Get Rich off Insider Stock Tips, Land Deals, and Cronyism That Would Send the Rest of Us to Prison (2011), and Extortion: How Politicians Extract Your Money, Buy Votes, and Line Their Own Pockets (2013).

According to the New York Times, Clinton Cash includes examples of a free-trade agreement in Columbia that benefitted the head of an oil company who had personally donated millions to the foundation, development projects in Haiti following an earthquake in 2010, and more than $1 million in payments to Bill Clinton by a major Canadian shareholder in the Keystone XL oil pipeline around the same time the State Department was debating the project.

As previously reported, a recent report from International Business Times detailed the Clintons’ involvement with the free-trade agreement between Columbia and the US, which included the fact that while then-Secretary of State Hillary Clinton was condemning human rights violations in Colombia, the Clinton family was also “forging a financial relationship” with the extensive petroleum company Pacific Rubiales, which is “at the center of Colombia’s labor strife.”

“We will see a pattern of financial transactions involving the Clintons that occurred contemporaneous with favorable U.S. policy decisions benefiting those providing the funds,” Schweizer wrote.

The New York Times noted that Schweizer’s book “largely focuses on payments made to Mr. Clinton for speeches, which increased while his wife served as secretary of state,” as shown by the fact that out of the “13 Clinton speeches that fetched $500,000 or more,” only two occurred during the years that Hillary Clinton was not secretary of state.

“During Hillary’s years of public service, the Clintons have conducted or facilitated hundreds of large transactions,” wrote Schweizer, who highlighted that fact that “some of these transactions have put millions in their own pockets.”

Presidential candidate and Senator Rand Paul (R-Kentucky), who has highlighted the phrase “Liberty, Not Hillary” in his campaign, also has a page on his website asking for any “additional information about the Clinton Foundation accepting foreign contributions.”

Business Insider called Clinton Cash the “blockbuster exposé” Paul has been waiting for to derail Hillary Clinton’s 2016 Presidential campaign.

Brian Fallon, a spokesman for Clinton’s campaign, told the Times that Schweizer’s book is “twisting previously known facts into absurd conspiracy theories.”

While Hillary Clinton’s aides have worked to label critical books as “conservative propaganda,” the New York Times predicted that Clinton Cash will do more damage than other books such as Edward Klein’s Blood Feud, which looks at the relationship between the Clintons and the Obamas, and Daniel Halper’s Clinton Inc.: The Audacious Rebuilding of a Political Machine, due to the fact that “major news organizations including The Times, The Washington Post and Fox News have exclusive agreements with the author  to pursue the story lines found in the book.”
