Wurman's scholarship focuses on administrative law, constitutional law, originalism, separation of powers, and the Fourteenth Amendment. In
The Second Founding: An Introduction to the Fourteenth Amendment (2020), he examined the original meaning of the Fourteenth Amendment's
Due Process,
Equal Protection, and
Privileges or Immunities Clauses. In 2021,
The Second Founding was named a Choice Outstanding Academic Title. In 2026,
SCOTUSblog highlighted Wurman's amicus brief in
Trump v. Barbara as one of the briefs supporting the Trump administration's position in the case, and
Reuters quoted him before oral argument on the scope of
birthright citizenship. Wurman also testified before the
United States Senate Committee on the Judiciary at a hearing titled
Protecting American Citizenship: Birthright Citizenship for Illegal Aliens and Tourists, alongside
Charles J. Cooper,
Amanda Frost, Alejandro Barranco, and
Peter Schweizer. The federal government cited Wurman's article
Jurisdiction and Citizenship in its merits brief and reply brief in
Trump v. Barbara. During oral arguments, Solicitor General
D. John Sauer referred the justices to Wurman's amicus brief. Wurman's birthright-citizenship arguments drew criticism from legal commentators and scholars. In
Lawfare, Chris Mirasola argued that Barnett and Wurman invoked a "nonexistent 'puzzle'" of international law to support their theory. In
Just Security, Marty Lederman and David J. Bier described their defense of Trump's executive order as "fundamentally flawed". A 2025
Cornell Law Review Online essay by Anthony M. Kreis, Evan D. Bernick, and Paul A. Gowder characterized the position as an "ahistorical, revisionist interpretation" of the Citizenship Clause. ==Selected works==
