A new investigative reporting bombshell being released in a couple weeks is expected to significantly derail Hillary Clinton's bid for the White House by shining a light on shady dealings with foreign entities via the Clinton Foundation, reported The New York Times on Sunday.

The 186-page book, "Clinton Cash: The Untold Story of How and Why Foreign Governments and Businesses Helped Make Bill and Hillary Rich," culminates a year-long investigation into the Clinton family, alleging that foreign entities regularly made donations to the Clinton Foundation, or paid Bill Clinton high speaking fees, in return for favors from Hillary's State Department.

Written by Peter Schweizer, president of the conservative-leaning non-partisan Government Accountability Institute (GAI) and former speech-writing consultant to George W. Bush, the book, set to be released May 5, is said to be "the most anticipated and feared book of a presidential cycle."

"During Hillary's years of public service, the Clintons have conducted or facilitated hundreds of large transactions" with foreign governments and individuals, Schweizer writes, according to the Times. "Some of these transactions have put millions in their own pockets." The Clintons earned at least $136.5 million between 2001 and 2012, he said.

Schweizer closely examines a number of over overseas speeches made by Bill Clinton, noting that these speeches increased during the years that his wife served as secretary of state. "Of the 13 Clinton speeches that fetched $500,000 or more, only two occurred during the years his wife was not secretary," he wrote. For example, Bill Clinton delivered 54 speeches in 2011, mostly overseas, raking in a total of $13.3 million, the Times reported.

The Times points out how successful Hillary Clinton's campaign has been at dismissing "critical books as conservative propaganda" and says her team is "planning another full-court press to diminish the book as yet another conservative hit job."

"Clinton Cash," though, according to the Times, is an entirely different beast - "potentially more unsettling, both because of its focused reporting and because major news organizations including The Times, The Washington Post and Fox News have exclusive agreements to pursue the story lines found in the book."

The Times continues: "He writes mainly in the voice of a neutral journalist and meticulously documents his sources, including tax records and government documents, while leaving little doubt about his view of the Clintons."

Members of the Senate Foreign Relations Committee have also been briefed on the book's findings, including Senator Rand Paul, R-Ky.

"There are certain businesses that the State Department oversees that are sensitive for security reasons," Paul told CNN's Wolf Blitzer earlier this month. "I believe and have been told that there is going to be information about donations to the Clinton Foundation that may or may not have had, or could possibly have had, influence over who gets to do business in various countries around the world."

Paul added, "I do know there will be [accusations made] that certain companies that were approved in countries that are sometimes our enemies or adversaries, these companies were approved and some of the shareholders of these countries gave large donations to the Clinton Foundation."
