Hillary Clinton put the State Department up for sale, with top aides pulling strings and doing favors for fat-cat donors to the Clinton Foundation — including a shady billionaire, according to smoking-gun emails released Tuesday.

The stunning revelations include how wealthy contributors seeking influence or prestigious government gigs could fork over piles of cash to get access to Clinton's inner circle, including top aides Huma Abedin and Cheryl Mills.

A Daily Caller News Foundation investigation traced the convoluted payment by TAQA — formally known as the the Abu Dhabi National Energy Company — to Muhammad Yunus' Grameen Bank. Yunus is a long-time friend and Clinton Foundation donor.

The oil company deal eventually put as much as $500,000 into President Bill Clinton's pockets via a speaking fee he got in Scotland.

These are not new concerns. People had been speculating that the Clinton Foundation had become a private version of the State Department, offering easy access to the State Department policy decision-making process for the wealthy and well-connected throughout Obama's first term.

At no time did the U.S. State Department ever say to Bill Clinton that any of his unbelievably lucrative speaking gigs represented a conflict of interest — even if there was reason to believe a foreign government or entities closely allied with a foreign government were paying. Recall the State Department praising the progress of Nigerian President Goodluck Jonathan as the president's ally invited Bill Clinton to give two speeches in exchange for $1.4 million dollars.
