August 2020, Jim Sciutto published a book called The Madman Theory in which Cohn said in response to Donald Trump saying that there were very good people on both sides of the protests which included white supremacists, "Citizens standing up for equality and freedom can never be equated with white supremacists, neo-Nazis, and the KKK." On March 6, 2018, Cohn announced his intention to resign; the announcement followed Trump's proposal to impose import tariffs on steel and aluminum, and Trump's cancellation of a meeting with end-users of steel and aluminum that Cohn had arranged in an attempt to dissuade the president from the planned tariffs. He was replaced by Larry Kudlow on April 2. Bob Woodward's 2018 book, Fear: Trump in the White House relates two instances in which Cohn removed draft letters from President Trump's desk, so that the President would not see them. One of the letters would have canceled a key trade agreement with South Korea, and the other would have withdrawn the US unilaterally from the NAFTA trade agreement with Canada and Mexico. Venture capital Following his departure from the White House, Cohn became an advisor and venture capital investor for companies in the cybersecurity, blockchain, and digital payments sectors. He currently serves on the Board of Spring Labs, a startup using blockchain technology to share consumer credit data, and Hoyos Integrity, a company employing biometric blockchain technology for secure communications and mobile payments. Cohn is also a key advisor for Machine Zone and Abryx, a biomaterial science company. At Hoyos Integrity, Cohn is deeply involved in the strategy and rollout of a next-generation secure mobile phone aimed at government and corporate customers. The company is also planning to launch a digital wallet — which employs more sophisticated biometrics — that consumers can use to make payments using a wide range of monetary assets, including bitcoin. The wallet will also be insured up to $1 million if hacked and will adhere to strict Know Your Client (KYC) and Anti Money Laundering (AML) regulations. The underlying technology of Hoyos' digital wallet and FIPS was born out of military-grade digital secure vault technologies. Unlike traditional digital wallets, it is designed to provide significant privacy protections to consumers as it does not mine their data, performs unique biometrics-based identity authentication on every transaction, and holds any digital fiat or cryptocurrency. The Hoyos wallet platform underwent stringent testing by U.S.
