The criminal accusations against Hillary Clinton just keep piling up. From peddling influence to foreign governments, to storing classified information on an unsecured e-mail server, she could be the first presidential candidate to run from a prison cell.

Now, the former secretary of state could face one of the most serious charges yet. A financial whistleblower says she could face prosecution by governments all over the world for her charity’s role in a 20-year crime spree that fleeced her donors and enriched her family.

Charles Ortel, a noted Wall Street analyst, has spent 15 months poring over the Clinton Foundation’s financial records and has concluded it is a “charity fraud” whose actions are “boldly illegal.”

While foreign sultans were donating millions to the secretary of state’s “charity,” and the Clintons and their cronies took huge pay-offs, her accountants were busy falsifying every part of the foundation’s paperwork to make it impossible to sort out.

There are “massive discrepancies between what some of the major donors say they gave to the Clinton Foundation” and the amount the Clintons said “they got from the donors,” Ortel wrote.

That fraud amounts to tens of billions of dollars – and it could mean serious jail time if prosecuted.

“In financial terms, the size of criminal activities directly involving the Clinton Foundation exceeds $2 billion,” Otrel wrote on his website. “Counting affiliated and indirect criminal activities, the size exceeds $50 billion.”

The Clintons had engaged in “a 20 year pattern of escalating, cross-border abuses,” Ortel added.

They have illegally solicited “charitable” donations in states where they lack legal authority to do so. Their tax returns are filed after the legal deadline, the information is incorrect, and they have never had a legal audit, he said.

Ortel has previously gained recognition for being accurate in his financial whistleblowing. His keen ability to read financial documents exposed the fact that GE’s stock was massively overvalued, shortly before it collapsed.

Now, he says he’s finding a persistent pattern of fraud in the woman who could be the next president of the United States.

A “substantial portion of Clinton Foundation” activity is anything but “’charitable’ or ‘tax-exempt’ in the accepted legal senses,” Ortel wrote.

What they are is serious crimes. While he doesn’t expect the Obama administration to take any serious legal action during a presidential election, Ortel is trying to get foreign nations to investigate and, if warranted, prosecute the Clintons.

“In some jurisdictions, such crimes are misdemeanors, in others they are more serious felonies,” he wrote. “I wonder why state, federal, and foreign regulators have allowed the Clinton Foundation to continue operating as it has done, illegally, for so long.”

The speculation that Hillary has bilked donors to enrich her political allies is well attested.

Of the half-billion dollars the Clinton Foundation raised between 2009 and 2012, $75 million went to charitable grants for the poor, according to The Federalist. That’s only 15 percent. But $110 million went to salaries, and $290 million was classified as “other expenses” – miscellaneous costs the Clintons did not bother to account for.

Eleven of its board members received at least $100,000 a year in salary in 2013.

“It seems like the Clinton Foundation operates as a slush fund for the Clintons,” said Bill Allison of the left-leaning Sunlight Foundation last April.

As long ago as 2013, the New York Times warned that the Clinton Foundation was “supervised by a rotating board of old Clinton hands, vulnerable to distraction and threatened by conflicts of interest.”

The nonprofit watchdog group Charity Navigator removed the foundation – formally known as the Bill, Hillary, and Chelsea Clinton Foundation – from its website because of its “atypical business model.”

So far, the mainstream media has ignored Ortel’s latest bombshell accusations. But with his track record, and her family’s reputation for sheer dishonesty, it’s only a matter of time before one of the serious criminal charges she is facing catch up to her.
