“John Sauer, the current US Solicitor General, is spearheading the legal defense of President Donald Trump’s controversial executive order seeking to restrict birthright citizenship.”

“Arguing before the Supreme Court of the United States, Sauer framed the administration’s position as a necessary correction to long-standing legal interpretations.”

“‘Unrestricted birthright citizenship contradicts the practice of the overwhelming majority of modern nations,’ Sauer told the court.”

“Since taking office as Solicitor General in 2025, Sauer has become one of the administration’s most important legal strategists, arguing major cases tied to executive power, immigration, and federal authority.”

“He previously represented Trump in the high-stakes Trump v. United States case, which resulted in a landmark ruling granting presidents broad immunity for actions within official duties.”

“Before his current role, Sauer served as Solicitor General of Missouri from 2017 to 2023, where he was involved in several politically charged legal efforts.”

“Notably, he signed onto a multistate legal challenge seeking to overturn the 2020 US presidential election results.”

“Sauer’s academic credentials reflect a traditional path through elite institutions: Undergraduate degrees in philosophy and electrical engineering from Duke University; Rhodes Scholar at the University of Oxford, where he studied theology; Master’s degree in philosophy from the University of Notre Dame; Law degree from Harvard Law School, where he served as an editor of the Harvard Law Review.”

“Early in his career, Sauer clerked for prominent conservative jurists, including US Supreme Court Justice Antonin Scalia.”

“He later worked in private practice, served as a federal prosecutor in Missouri, and founded his own law firm, building a reputation in constitutional and appellate litigation.”
