NERMEEN SHAIKH: We turn now to look at the man who is said to have out-Koched the Koch brothers in the 2016 election. His name is Robert Mercer, a secretive billionaire hedge-fund tycoon who, along with his daughter Rebekah, is credited by many with playing an instrumental role in Donald Trump’s election.

Trump’s chief strategist, Steve Bannon, said, quote, “The Mercers laid the groundwork for the Trump revolution. Irrefutably, when you look at donors during the past four years, they have had the single biggest impact of anybody, including the Kochs.” Before Bannon and Kellyanne Conway joined the Trump campaign, both worked closely with the Mercers. The Mercers bankrolled Bannon’s Breitbart News, as well as some of Bannon’s film projects. Conway ran a super PAC created by the Mercers to initially back the candidacy of Ted Cruz.

The Mercers also invested in a data mining firm called Cambridge Analytica, which claims it has psychological profiles of over 200 million American voters. The firm was hired by the Trump campaign to help target its message to potential voters.

While the Mercers have helped reshape the American political landscape, their work has all been done from the shadows. They don’t speak to the media and rarely even speak in public.

AMY GOODMAN: During the entire presidential campaign, they released just two statements. One was a defense of Donald Trump shortly after the leak of the 2005 Access Hollywood tape that showed Trump boasting about sexually assaulting women. The Mercers wrote, quote, “We are completely indifferent to Mr. Trump’s locker room braggadocio.” They went on to write, “America is finally fed up and disgusted with its political elite. Trump is channeling this disgust and those among the political elite who quake before the boombox of media blather do not appreciate the apocalyptic choice America faces on November 8th. We have a country to save and there is only one person who can save it. We, and Americans across the country and around the world, stand steadfastly behind Donald J Trump.” Those were the words of Robert and Rebekah Mercer one month before Trump won the election.

Since the election, Rebekah Mercer joined the Trump transition team, and Robert Mercer threw a victory party of sorts at his Long Island estate. It was a hero and villain’s costume party. Kellyanne Conway showed up as Superwoman. Donald Trump showed up as himself.

To talk more about the Mercers, we’re joined now by Jane Mayer, staff writer at The New Yorker, her latest piece headlined “The Reclusive Hedge-Fund Tycoon Behind the Trump Presidency: How Robert Mercer exploited America’s populist insurgency.” Jane is also author of Dark Money: The Hidden History of the Billionaires Behind the Rise of the Radical Right, which just came out in paperback.

Jane Mayer, welcome back to Democracy Now! The beginning of the piece talks about a former colleague of Mercer’s saying, “In my view, Trump wouldn’t be president if not for Bob.” Explain who Robert Mercer is.

JANE MAYER: Well, he’s a, as you’ve mentioned, a New York hedge-fund tycoon. He’s a computer scientist, a kind of a math genius and uber-nerd, who figured out how to game the stocks and bonds and commodities markets by using math. He runs something that’s kind of like a quant fund in Long Island, and it’s called Renaissance Technologies. He’s the co-CEO. And it just mints money. So he’s enormously wealthy. He earns at least $135 million a year, according to Institutional Investor, probably more.

And what he’s done is he has tried to take this fortune and reshape, first, the Republican Party and, then, America, along his own lines. His ideology is extreme. He’s way far on the right. He hates government. Kind of—according to another colleague, David Magerman, at Renaissance Technologies, Bob Mercer wants to shrink the government down to the size of a pinhead. He has contempt for social services and for the people who need social services.

And so, he has been a power behind the scenes in Trump’s campaign. He kind of rescued Trump’s campaign in the end, he and his daughter. And, you know, most people think Trump was the candidate who did it on his own, had his own fortune, and he often boasted that he needed no help and had no strings attached, and he was going to sort of throw out corruption. And, in fact, there was somebody behind the scenes who helped enormously with him.

AMY GOODMAN: Talk about that moment, when you talk about them saving Donald Trump, which has become particularly relevant today. This was the time that Manafort was forced out as the campaign manager for Donald Trump. The campaign was in disarray. He was being forced out because of his ties to Ukraine and Russia and the money that was being revealed that he might or might not have taken. So, take it from there.

JANE MAYER: Well, right. And this was—really, Trump’s campaign was—it was floundering. It was in August, and there was headline after headline that was suggesting that Paul Manafort, who had been the campaign manager, had really nefarious ties to the Ukrainian oligarchs and pro-Putin forces. And it was embarrassing. And eventually, after a couple days of these headlines, he was forced to step down.

And the campaign was, you know, spinning in a kind of a downward spiral, when, at a fundraiser out in Long Island, at Woody Johnson’s house—he’s the man who owns the Jets—Rebekah Mercer, the daughter of this hedge-fund tycoon, Bob Mercer, sort of cornered Trump and said, “You know, we’d like to give money to your campaign. We’ll back you, but you’ve got to try to, you know, stabilize it.” And basically, she said, “And I’ve got just the people for you to do the job.”

And they were political operatives who the Mercer family had been funding for a couple of years, the main one being Steve Bannon, who is now playing the role to Trump—he’s the political strategist for Trump—that’s the role he played for the Mercer family prior to doing it for Trump. So, these are operatives who are very close to this one mega-donor. The other was Kellyanne Conway, who had been running this superfund, as you mentioned in your introduction, for the Cruz campaign, that was filled with the money from the Mercers. And so she became the campaign manager. Bannon became the campaign chairman. And a third person, David Bossie, whose organization Citizens United was also very heavily backed by the Mercer family, he became the deputy campaign manager. So, basically, as Trump’s campaign is rescued by this gang, they encircle Trump. And since then, they’ve also encircled Trump’s White House and become very key to him. And they are the Mercers’ people.

NERMEEN SHAIKH: Well, Jane Mayer, Rebekah Mercer, whom you mentioned, is known—described as “the first lady of the alt-right.” Now, you tried to get Rebekah and Robert Mercer to speak to you for this piece. What response did you get?

JANE MAYER: Oh, I mean, it was hopeless, clearly, from the start. They have nothing but disdain for, you know, the mainstream media. Robert Mercer barely speaks even to people who he works with and who know him. I mean, he’s so silent that he has said often that he—or to a colleague, he said once—I should correct that—that he much prefers the company of cats to humans. He goes through whole meetings, whole dinners, without uttering a word. He never speaks to the media. He’s given, I think, one interview I know of, to a book author, and who described him as having the demeanor of an icy cold poker player.

His daughter, Rebekah Mercer, who’s 43 and has also worked at the family’s hedge fund a little bit and is a graduate of Stanford, she’s a little more outspoken. She has been in fundraising meetings on the right. She has spoken up—and very loudly and irately, actually. But she doesn’t speak to the press. And so, I had very little hope that they would.

AMY GOODMAN: Can you talk about when they first met, the Mercers, Robert and Rebekah Mercer, first met Andrew Breitbart, and what that progression was and how they came to be linked up with Bannon?

JANE MAYER: Well, sure. The Mercer family, Robert and his daughter Rebekah, met Andrew Breitbart back—I think it was late 2011 or early 2012, speaking at a conference of the Club for Growth, another right-wing group. And they were completely taken with Andrew Breitbart. He was pretty much the opposite kind of character from Bob Mercer. Breitbart was outspoken and gleefully provocative and loved to offend people and use vulgar language just to catch their attention. And you’ve got this kind of tight-lipped hedge-fund man from the far right who just fell for Breitbart big time.

And he—mostly what he was captivated by, I think, was Breitbart’s vision, which was, “We’re going to”—he said, “Conservatives can never win until we basically take on the mainstream media and build up our own source of information.” He was talking about declaring information warfare in this country on fact-based reporting and substituting it with their own vision. And what he needed, Breitbart, at that point, was money. He needed money to set up Breitbart News, which was only just sort of a couple of bloggers at that point.

AMY GOODMAN: And talk about Breitbart News, about what the alt-right represented, whether we’re talking about anti-Semitism or white supremacy, and why they were attracted to this.

JANE MAYER: Well, I mean, you know, it changed. What happened was—I mean, it started as a—Andrew Breitbart had helped The Huffington Post get set up. And his idea was that he was going to launch The Huffington Post of the right. And so, he was setting it up, and his very close friend was Steve Bannon. And Bannon had been in investment banking. So Bannon got the Mercers to put $10 million into turning this venture into something that was really going to pack a punch. And they were just about to launch it in a big day—big way. They were a few days away from it, when Andrew Breitbart died. That was in March of 2012. He was only 43, and he had a sudden massive heart attack. And so, this operation was just about to go big. It was leaderless. And that’s when Steve Bannon stepped in and became the head of Breitbart News.

And in Bannon’s hands, it became a force of economic nationalism and, in some people’s view, white supremacism. It ran, you know, a regular feature on black crime. It hosted and pretty much launched the career of Milo Yiannopoulos, who’s sort of infamous for his kind of juvenile attacks on women and immigrants and God knows what. You know, just it became, as Bannon had said, a platform for the alt-right, meaning the alternative to the old right, a new right that was far more angry and aggressive about others, people who were not just kind of the white sort of conservatives like themselves.

AMY GOODMAN: So they made a $10 million investment in Breitbart. They owned it—

JANE MAYER: A 10 million.

AMY GOODMAN: —co-owned it.

JANE MAYER: They became the sponsors, really, behind it. And it’s interesting to me that—one of the things I learned was that Rebekah Mercer, this heiress, who’s had no experience in politics, is so immersed in running Breitbart News at this point. I mean, she—her family is the money, big money, behind it. That she reads every story, I’m told, and flyspecks, you know, typos and grammar and all that kind of thing. I mean, there is a force behind Breitbart News that people don’t realize, and it’s the Mercer family. So, anyway, it became very important, increasingly, on the fringe of conservative politics, because it pushed the conservatives in this country towards this economic nationalism, nativism, anti-immigration, pro-harsh borders, anti-free trade, protectionist. And it spoke the language of populism, but right-wing populism.

NERMEEN SHAIKH: And, Jane Mayer, I mean, as you’ve said, one of the things that has made the Mercers so successful in their political interventions is precisely this, the way in which they’ve invested in an alternative media and information network, of which Breitbart is, of course, a very significant part. But can you also talk about the Government Accountability Institute, which you discuss in your piece?

JANE MAYER: Sure. I mean, and this was, you know, very much a design. You’ve got this family with all the money in the world, wanting to change American politics. And they hadn’t been very effective in their earlier efforts at this, until they joined forces with Steve Bannon, who’s a very sort of farsighted strategist who kind of sees the big picture and understands politics. And so, he very much focused their efforts on this information warfare, first with Breitbart, $10 million into that. And then, after 2012, when the Mercers were very disappointed that Obama got re-elected, at Bannon’s direction, they started to fund a brand-new organization called the Government Accountability Institute. It’s based in Tallahassee. It’s small. It’s really a platform for one major figure, Peter Schweizer, who is a conservative kind of investigative reporter.

And what they did with this organization, which the Mercers poured millions of dollars into, was they aimed to kind of create the—drive the political narrative in the 2016 campaign. They created a book called Clinton Cash, which was a compendium of all the kinds of corruption allegations against the Clintons. And they aimed to get it into the mainstream media, where it would pretty much frame the picture of Hillary Clinton as a corrupt person who couldn’t be trusted. And their hope was that they would mainstream this information that they dug up. It was like an opposition research organization, sort of masked as a charity and nonprofit. And they took this book, Clinton Cash, gave it to The New York Times exclusively, early, and the Times then ran with a story out of it, that they said they corroborated. But they ran with it, nonetheless, on their front page, which just launched this whole narrative of Hillary Clinton as corrupt. And it just kept echoing and echoing through the media after that. So, it was a real home run for them. A year later, they made a movie version of it also, which they launched in Cannes.

AMY GOODMAN: You’re talking about Peter Schweizer and, as well, the Mercers. What about Cambridge Analytica, in addition to the Government Accountability Institute? And also, the Mercers’ obsession with the Clintons, the whole issue that you write about.

JANE MAYER: Well, this is something that—

AMY GOODMAN: They’re talking about they’re murderers.

JANE MAYER: I mean, really—I mean, one of the—one of the challenges of writing about the Mercers, for me, was to figure out—OK, so they’re big players. There are players in the Democratic Party who put in tons of money, too. They’re not the only people who put money into politics. But they’re maybe the most mysterious people who put money into politics. Like nobody really knew what do they believe, what’s driving them. And so, I was trying to figure that out.

And what I finally was able to do what was talk to partners and people they work with in business and people who’ve known them a long time, who paint this picture of them as having these really peculiar beliefs, and based on kind of strange far-right media. Among their beliefs are that—Bob Mercer has spoken to at least three people who I interviewed, about how he is convinced that the Clintons are murderers, literally, have murdered people. Now, you hear that on the fringes sometimes when you interview people who are ignorant, but these are people who are powerful, well educated and huge influences in the country. And Bob Mercer was convinced that the Clintons are murderers. OK, so he’s driven by this just hatred of the Clintons and, coming into 2016, is determined to try to stop Hillary Clinton, and looking for a vehicle who would do that, who eventually becomes Trump.

AMY GOODMAN: Jane Mayer, we’re going to come back to this conversation. Jane Mayer is staff writer at The New Yorker. Her piece is “The Reclusive Hedge-Fund Tycoon Behind the Trump Presidency: How Robert Mercer exploited America’s populist insurgency.” And her book is out in paperback, Dark Money: The Hidden History of the Billionaires Behind the Rise of the Radical Right. There is so much to talk about. Stay with us.
