A Daily Caller News Foundation investigation reveals that Bill and Hillary Clinton received at least $100 million from autocratic Persian Gulf states and their leaders, potentially undermining Democratic presidential candidate Hillary's claim she can carry out independent Middle East policies.

As a presidential candidate, the amount of foreign cash the Clintons have amassed from the Persian Gulf states is "simply unprecedented," says national security analyst Patrick Poole.

"These regimes are buying access. You've got the Saudis. You've got the Kuwaitis, Oman, Qatar and the UAE. There are massive conflicts of interest. It's beyond comprehension," Poole told TheDCNF in an interview.

Overall, the Clinton Foundation has received upwards of $85 million in donations from five Persian Gulf states and their monarchs, according to the foundation's website.

The Clinton Foundation's ties go beyond support from governments. Four billionaire Saudis, along with groups the Dubai Foundation and Friends of Saudi Arabia, contributed another $30 million to the Clinton Foundation, according to the foundation's website.

Yet as secretary of state, Clinton consciously and actively sought to legitimize the sheikdoms through many new Department of State programs.

It's unclear what kind of promises or concessions the Clintons may have given the monarchs in return for their lavish financial support over the years, but last month the candidate reversed her long-standing support for fracking.

Hillary's new position, unveiled last month at a CNN presidential debate with Democratic opponent Sen. Bernie Sanders, put her in alignment with the Gulf State policy that opposes North American oil and gas fracking.
