The History of Proof

A regularly updated catalogue of key events in the history of this digital media outlet.

October 30, 2017: Substack co-founder Hamish McKenzie graciously asks me to create a newsletter on his new platform. Overwhelmed by my work on Twitter covering the Trump-Russia scandal, I stupidly don’t reply to Hamish’s email.

September 25, 2020: The podcast that gives this website its name and logo—Proof: A Pre-election Special—is launched. A ten-episode limited series intended to summarize some key revelations in the sprawling, 2,500-page Proof trilogy, the podcast becomes a Top 10 Government podcast on Apple Podcasts in 31 nations, reaching #2 in America. The podcast is produced by Pablo Salzman of Connect3, a division of Cineflix Media, with former Vice contributing editor Thomas Morton as co-host.

January 6, 2021: Incited by then-president Donald Trump, thousands of pro-Trump irregulars violently assault the United States Capitol. Nearly 1,000 breach the building itself. Five people die and more than 130 police officers are injured. The ensuing effort to impeach Trump a second time, something that had never before happened in U.S. history, achieves its end on January 13, 2021—giving birth to Proof the following day.

January 9, 2021: Less than 120 hours before the founding of ProofGavin McInnes, the founder of the white supremacist Proud Boys, threatens to sue me on Parler over false claims that my research on the Proud Boys’ role in the January 6 attack was inaccurate as to the garb worn by a key contingent of Proud Boys at the Capitol: “blaze-orange” hats. This research—first posted on Twitter, and then, thereafter, a centerpiece of two early articles at the Proof Substack—is very quickly vindicated and duplicated by media outlets across the United States, with Gavin McInnes’ threat serving as one of several inspirations for Proof focusing intently on revealing the truth about what happened in Washington on January 6.

January 14, 2021: The Proof Substack is founded. At its founding, it has a simultaneous “News,” “Politics,” and “Culture” categorization under Substack’s subject-area rubric.

Per DCM, “American journalist Seth Abramson alleges that Eduardo Bolsonaro attended a meeting that conspired against American democracy the day before the [January 6] invasion [of the U.S. Capitol]. The exclusive article lists ten connections between Eduardo and the [insurrection]. Brazilian taxpayers now have several questions: What did Eduardo Bolsonaro do in D.C. at the beginning of [2021]? What was the subject of his meeting with [Trump adviser] Michael Lindell? Did he attend a meeting at Trump International Hotel?” Similar credit was given by Brazilian publications Congress Em Foco (link), Revista Forum (link), Brasil 247 (link), Ler Agora (link), DCI Digital (link), GGN: O Jornal de Todos os Brasis (link), Poliarquia (link), Farol da Bahia (link), Brasil Independente (link), MBL News (link), Pensar Piauí (link), BNC Amazonas (link), and via several follow-ups in Diário do Centro do Mundo (see, e.g., here).
