In 1997, after Harvard University president Neil Rudenstine rejected the Department of Government's recommendation and denied his tenure, Berkowitz challenged the process by which Rudenstine reached his decision through Harvard's internal grievance procedure.[7] Eventually, in 2000, he brought a lawsuit for breach of contract against Harvard alleging flaws in both the tenure review process and the grievance procedure.[8] In 2003, the Massachusetts Supreme Judicial Court dismissed his case.[8]
In October 2020 he tested positive for coronavirus following meetings with senior officials at 10 Downing Street and the Foreign Office in London, and with officials in Budapest and Paris. Some U.S. State Department officials were angered by Berkowitz's trip, arguing that it was unnecessary.[15]
During his tenure at the State Department, Berkowitz served as executive secretary to the Commission on Unalienable Rights.[16] During Berkowitz's tenure, the Commission produced a Report of the Commission on Unalienable Rights, which emphasizes America's dedication to inalienable rights — the rights shared by all people — and the foundations of human rights that can be found across cultures throughout the world.[17]
Following his tenure at the State Department, Berkowitz resumed his duties at the Hoover Institution and became a columnist at RealClearPolitics. He also writes for other publications and is the author of several books on political philosophy and on international law, most recently Constitutional Conservatism (Hoover Press, 2013).[19]
