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.

In an April 2009 message to Abedin and Mills, Doug Band, who was overseeing the Clinton Foundation at the time, urgently asked for a meeting between a top US official and Gilbert Chagoury — a major donor to the Clinton family charity.

“We need to speak to the substance person re Lebanon. As you know, he’s [Chagoury] key guy there and to us and is loved in lebanon,” wrote Band, in a clear attempt to suck up to a big donor to the foundation.
