Since Mitt Romney’s loss in the 2012 election,
the Mercers have drifted ever further out of the orbit of Planet Koch,
building up their own entities, including #Breitbart #News,
#Cambridge #Analytica (the data startup),
and the ironically named #Government #Accountability #Institute,
all of them featuring #Steve #Bannon, the self-described economic nationalist, in top slots
—until he joined the White House.
Cambridge Analytica, on whose board Bannon served, and Breitbart, where he was the chief executive, are private companies.
#GAI, which produced the campaign-season book
"Clinton Cash: The Untold Story of How and Why Foreign Governments and Businesses Helped Make Bill and Hillary Rich", by Peter Schweizer,
is a nonprofit organization.
Schweizer’s book, together with an accompanying movie executive-produced by #Rebekah Mercer, was designed to sully the reputation of Democratic presidential nominee Hillary Clinton.
It was part of a Bannon-crafted strategy to steer the sort of smears that usually bubble up from the right-wing fever swamps directly into the mainstream media.
It worked; in 2015 the New York Times and the Washington Post both made exclusive agreements with the GAI to report on advance excerpts of Clinton Cash.

#Bannon was wealthy before he met up with the Mercers,
first through his work as a banker for Goldman Sachs back when it was a privately held company,
and then through his own privately held ventures in movie-making and consulting.
Though Bannon’s wealth, when compared to that of Betsy DeVos, makes him a pipsqueak in the Trump money universe
(assets worth between $12 million and $54 million, according to the New York Times),
it nonetheless derives primarily from privately held entities.
