During and after the 2016 US presidential election, Mensch's political commentary and social media accounts promoted numerous various conspiracy theories about the Russian government, Donald Trump and various individuals in Trump's circle. Mensch claims that she has seen evidence that Vladimir Putin had Andrew Breitbart murdered to make room for Steve Bannon at "Breitbart". She has stated that the 2017 Istanbul nightclub shooting was a Russian false flag operation, with Russian intelligence operatives posing as ISIL terrorists; that onetime Trump chief political strategist Steve "Bannon and his team" were behind bomb threats to Jewish community centres; and that Russian intelligence operatives planted Hillary Clinton's emails on Anthony Weiner's laptop just before the 2016 presidential election. Mensch has also accused numerous people and organizations of being Russian "shills", "moles" and "agents of influence", including Facebook founder Mark Zuckerberg, Peter Thiel, Israeli Prime Minister Benjamin Netanyahu and elements of Mossad (Israel's intelligence service).
