number one best-selling book on Amazon.com three days before its official release, as a result of pre-order sales. Unfreedom of the Press also became a New York Times #1 best-seller on June 6, 2019, in the combined print & e-book nonfiction and hardcover nonfiction categories. Lloyd Green was critical of the book in The Guardian writing that the book "is not exactly fan fiction but it can get ahead of itself when discussing the special counsel's conclusions, ending up sounding like the 'fake news' the author and Trump both purport to abhor."

The study found that he utilized "outrage speech or behavior at a rate of more than one instance per minute." In How Democracies Die, Harvard University political scientists Daniel Ziblatt and Steven Levitsky write that Mark Levin was among the popular right-wing talk radio hosts who "helped to legitimate the use of uncivil discourse" in American politics, and contribute to the erosion of democratic norms.
