Media Matters said the author of "Clinton Cash", Peter Schweizer, "has a Long History Of Errors, Retractions, And Questionable Sourcing."
In a major speech at the end of June, Donald Trump recited a number of claims from Clinton Cash, a 2015 bestselling investigation into donations to the Clinton Foundation.
Politifact investigated one of the claims in great depth: Did "Hillary Clinton’s State Department approve the transfer of 20 percent of America’s uranium holdings to Russia, while nine investors in the deal funneled $145 million to the Clinton Foundation — $145 million dollars?"
Politifact rated Trump's claim "Mostly False":
"There’s a grain of truth in this claim. Clinton’s State Department was one of nine government agencies to approve Russia’s acquisition of a company with U.S. uranium assets. Nine people related the company at some point in time donated to the Clinton Foundation, but we only found evidence that one did so "while" the Russian deal was occurring. The bulk of the $145 million in donations came two years before the deal." [And most of the $145 million came from Frank Giustra, who says he had sold all of his stakes in Uranium One at least 18 months before Hillary became Secretary of State.]
In 2007, Frank and President Bill Clinton launched the Clinton Giustra Enterprise Partnership, with the focus of creating social and economic development programs in parts of the world where poverty is widespread, including Colombia, Peru, Mexico, and Haiti.
Clinton Giustra Enterprise Partnership (Canada) gave more than $25,000,000 to the Clinton Foundation in the second quarter of 2016.
