23 min readJul 30, 2019


One of the more untold stories of the saga is Psy-Group, a social media manipulation organisation in the same vein as Cambridge Analytica that made its way into the Trump campaign.

Joel Zamel was born in Australia in 1986.

In 1993, Nigel Oakes founded the organisation Strategic Communication Laboratories, which would later receive financial support from Lord Marland.

In 2003, Alexander Nix joined the organisation SCL Group.

After 2004, Nader started to work for Blackwater as a business agent in Iraq.

During the Presidency of George W. Bush, Nader and John Hannah worked with each other on foreign policy related to Iraq.

In 2005, SCL Group relaunched as a psychological warfare-focused organisation after Sir Geoffrey Pattie was installed as the chairman, and with assistance from Nigel Oakes’s brother, Alexander Oakes.

On July 20, 2005, SCL Group Limited was incorporated by Nigel Oakes, Alexander Oakes and Nix, with John Bottomley as Company Secretary.

In October 2005, Roger Gabb became a director at SCL Group, and was officially appointed on November 10, 2005.

At some stage, SCL Group partnered with the organisation Iota Global.

In 2007, SCL Group paid $20,000.00 to the lobbying organisation Global Policy Partners in Washington, DC to help advertise the company in the United States, which led to a business relationship with the Pentagon to conduct surveys in Iran and Yemen.

On January 12, 2007, Julian Wheatland resigned as Director at SCL Group Limited.

On December 20, 2007, Wheatland was appointed as a director at SCL Group Limited.

On December 1, 2008, Geoffrey Pattie resigned as Director at SCL Group Limited.

A few years later, the organisation SCL Social was founded as a non-profit humanitarian psychological warfare organisation.

In 2010, Nix visited the United States to learn about the consulting industry in American politics, but left dejected.s

The same year, Wikistrat was founded by Joel Zamel and Daniel Green in Israel. It later relocated to Washington, DC. John Hannah later became a member of the advisory council, as did David Shedd, Michael Hayden, Dennis Ross, Elliott Abrams, Sandra Charles, Steve Cambone and Jerry Brennan.

On August 23, 2010, Erik Prince gave a video deposition at the Hotel Rotana in Abu Dhabi, where Prince was asked about his relationship with George Nader.

VIDEOGRAPHER: “What about a man — excuse me. What about a man named George Nader? What did he do for you?”
ERIK PRINCE: “He was a — kind of a business development consultant that we retained in Iraq for a while.”

At some stage, one of Zamel’s firms worked with both Oleg Deripaska and Dmitry Rybolovlev, who hired the firm for psychological campaigns against their business rivals.

In 2012, Farage and Bannon met each other. The same year, Kaiser met Nix for the first time at a sushi restaurant with Mongolian clients, although Kaiser refused to join the company at the time.

In February 2012, Nix and his girlfriend, Caroline Paus, bought a home in West London for £4.5 million.

On December 7, 2012, Nix resigned as Director at SCL Group Limited.

In 2013, SCL Elections spun off to found Cambridge Analytica in the United States, to which Stephen Bannon would later sit on the board. Around this time, Robert and Rebekah Mercer entered discussions with Nix and Christopher Wylie for an acquisition —having been introduced to the company by Bannon — while SCL was retained by numerous officials from Trinidad and Tobago, which led to AggregateIQ being brought in to assist. The Trinidad Project also had Wylie, Thomas Borwick and Mark Gettleson working on it.

In January 2013, a former intern of SCL Elections was contacted by Nix, where they discussed Palantir as a method to extract data.

In the autumn of 2013, Wylie met Bannon.

In 2014, Cambridge Analytica was approached by Cambridge University psychologist Aleksandr Kogan, where Kogan suggested data collection on Facebook users.

On March 31, 2014, Bottomley resigned as Company Secretary at SCL Group Limited, as he was replaced with Alexander Oakes.

Cambridge Analytica worked with and paid researchers at Cambridge University to harvest psychological profiles of American Facebook users through the use of an online survey, more specifically from the Cambridge University Psychometrics Center.

Before February 2015, Senator Ted Cruz’s presidential campaign entered a working relationship with Cambridge Analytica, which totalled over $5.8 million in services. The organisation set up operations in Senator Cruz’s campaign headquarters in Houston, TX, and worked closely with Chris Wilson.

Cambridge Analytica also entered a working relationship with the campaign of Ben Carson, which paid a total of $220,000.00.

Around this time, Cambridge Analytica also pursued business relationships with Carly Fiorina, Scott Walker, Senator Marco Rubio and Governor Chris Christie. Jeb Bush also visited the offices of Cambridge Analytica and met with Nix directly in London.

Around June 2015, Zamel reached out to Michael Flynn — having been introduced to Flynn by Bijan Kian — in an attempt to add Flynn to Wikistrat’s advisory board, which led a conversation about the subject. Zamel would also be introduced to various Pentagon officials by Adam Lovinger, a Pentagon strategist and an associate of the Flynn Intel Group, after a Navy Commander brought Zamel to the Office of Net Assessment.

“‘Joel Zamel has never met Michael Flynn,’ Zamel’s attorney, Marc Mukasey, told The Daily Beast via telephone. Asked about Zamel’s relationship with Kian, Mukasey hung up.” — The Daily Beast

On July 7, 2015, Kenneth Vogel and Tarini Patel published the article “Cruz partners with donor’s ‘psychographic’ firm” in Politico, which revealed the existence of Cambridge Analytica’s relationship with the 2016 United States presidential campaign.

In the fall of 2015, the offices of Cambridge Analytica were relocated from Washington, DC to Alexandria.

In March 2016, George Birnbaum requested the e-mail address of Rick Gates from Eckart Sager — a mutual associate — to pitch the organisation Psy-Group to him. During this time, Birnbaum worked with numerous Psy-Group employees on “Project Rome” to refine proposals for the Trump campaign. Psy-Group hired the law firm Covington & Burlingh to legally review the proposal.

A few days after being hired by the Trump campaign with Paul Manafort, Gates and Birnbaum met with each other at the Mandarin Oriental hotel in Washington, DC, where they discussed Joel Zamel and Psy-Group as a potential way of swaying Republican delegates.

On March 2, 2016, Foreign Secretary Philip Hammond stated during a speech at Chatham House that the only country interested in the United Kingdom leaving the European Union would be Russia.

On March 4, 2016, Ben Carson officially ended his presidential campaign.

On Friday, March 11, 2016, the Russian Embassy in London published a press release, which condemned the British Government’s efforts to lace the Brexit vote with Russian interests. An employee of Leave.EU then sent an e-mail to Banks and Wigmore, where it was suggested to publish a statement of support for the Russian Embassy’s condemnation of the British Government’s stance, although Wigmore said they should contact Ambassador Yakovenko.

In April 2016, Birnbaum drafted his first document to refine proposals that would then be presented to the Trump campaign for social media manipulation. Part of the proposal featured social media messages targeted at criticising Senator Ted Cruz.

On April 14, 2016, SCL USA Limited officially renamed itself to Cambridge Analytica (UK) Limited.

Around this time, Nix met with Brad Parscale and convinced him to use Cambridge Analytica as part of the Trump campaign.

In May 2016, Rick Gates agreed to work with the Trump campaign’s correspondence coordinator to prevent people from arranging meetings with Russians moving forward.

In early May 2016, Zamel sent an e-mail to Newt Gingrich, where he offered Psy-Group’s services to the Trump campaign, and offered to meet in Washington, DC. Gingrich forwarded the e-mail to Jared Kushner, and Kushner inquired with numerous Trump campaign officials, including Brad Parscale — Parscale said they did not need Zamel.

In the summer of 2016, Bannon left his position as Vice President of the Board at Cambridge Analytica.

In June 2016, both Zamel and Nader attended an international economic forum in St. Petersburg, Russia separately, as Zamel later approached Nader to request a meeting — having been introduced to Nader by John Hannah — as he wanted to assist with the Trump campaign financially. Nader, at the time, represented Crown Prince Mohammed as a confidential emissary.

On June 24, 2016, the United Kingdom voted to leave the European Union, with Leave winning with 52% of the vote.

On July 17, 2016, Banks tweeted: “I’m buying gold at the moment & big mining stocks …”

“‘So what?’ Banks shrugged. He took a look, he said. He’s a businessman, after all. He has a stake in diamond mines in South Africa and a uranium mine in Niger. But, he insists, he didn’t do any deals with the Russians — no gold, no diamonds.” — The Washington Post

Around July 20, 2016, George Nader started to inquire on behalf of Sheikh Mohammed bin Zayed al-Nahyan about potential ways to support Trump.

In the summer of 2016, Isabel Oakeshott was granted access to Banks’ e-mails to assist in her ghostwriting of the book, “The Bad Boys of Brexit”.

“I can confirm an approach by Cambridge Analytica [prior to November last year] and can confirm that it was rejected by WikiLeaks.” — Julian Assange, October 25, 2017

In August 2016, Wigmore may have sent an e-mail to a contact at the Russian Embassy in London, which contained legal documentation and the Federal Bureau of Investigation’s indictment surrounding George Cottrell.

The same month, lawyers for Facebook wrote a letter to Wylie and informed him that the data used by Cambridsge Analytica had been gained illicitly and that Global Science Research should not have access to it.

Nix also sent an e-mail to multiple people, including Rebekah Mercer, where he stated he had sent an e-mail to Julian Assange in August 2016 to seek access to the e-mails from Hillary Clinton’s private server to turn it into a searchable database for the Trump campaign.

On August 3, 2016, at 04:00 P.M., Nader and Zamel visited a Manhattan hotel, when Nader was contacted via telephone by Prince to visit Trump Tower. Nader and Zamel then met with Donald Trump Jr. and Stephen Miller at Trump Tower for 30 minutes. The conversation was about Psy-Group, and Nader offered Trump. Jr to meet with a Saudi Arabian prince, but ultimately both did not progress further.

In mid-August 2016, Alex van der Zwaan sent a text message to Gates.

On August 15, 2016, Hillary For America issued out an e-mail titled “Trump Owes Americans Answers on Troubling Ties to Pro-Kremlin Forces”, which featured the names of people such as Gates, Paul Manafort, Carter Page, Lt. Gen. Michael Flynn, Michael Caputo, Richard Burt, Howard Lorber and Boris Epshteyn.

The next day, on August 16, 2016, Gates was interviewed by agents from the Federal Bureau of Investigation, where he provided misleading information on his interactions with Mercury back in 2012.

On August 17, 2016, Trump named Bannon as the Chief Executive of the Trump campaign.

On August 19, 2016, Ambassador Yakovenko met with both Banks and Wigmore.

In September 2016, van der Zwaan contacted Gates over work that they did together for the Party of Regions. In the same month, the United States Department of Justice informed Gates, Manafort and Davis-Manafort International that it sought to determine whether they had acted as agents of a foreign principal under the Foreign Agents Registration Act without registering.

The same month, Nix attended the Concordia Summit in New York, where he hosted a presentation about Cambridge Analytica’s work in the United States.

From around October 2016, Nader became more closely tied to the Trump campaign, as he met with Kushner, Flynn and Bannon on various occassions.

On December 15, 2016, Sheikh al-Nahyan met with Lt. Gen. Flynn, Kushner and Bannon at Trump Tower, although Nader either attended the meeting or he greeted Emirati officials as they departed.

“Then on December 15, 2016, Kushner, Flynn, and Bannon secretly met at Trump Tower with Nader and MBZ. That meeting, which the crown prince did not give advance notice about to the Obama administration, set off red flags with national security officials at the time. It was also one of several meetings with foreign officials that Kushner failed to disclose on his security clearance request form.” — New York Magazine

“Mr. Zamel asked his contacts whether they were close to top officials in the coming White House, according to the person close to Wikistrat.

The same month, the United States Department of State awarded SCL a $500,000.00 contract to provide target audience research.

On February 16, 2017, Cadwalladr used Google’s auto complete search to try and find information about Trump and his war with the mainstream media, after she searched Twitter and found both anti- and pro-Trump sentiments over his declaration that CNN was fake news, which led to her finding information about Robert Mercer.

On February 17, 2017, Kaiser visited the Ecuadorean Embassy to meet with Assange to discuss Assange’s current situation for 20 minutes.
