D. John Sauer — Solicitor General of the United States
Agency: United States Department of Justice Role: 49th Solicitor General of the United States (April 4, 2025 – present) Severity: P1
Bio and Background
Dean John Sauer was born on November 13, 1974, in St. Louis, Missouri. He attended Saint Louis Priory School, a Catholic day school run by Benedictine monks. He graduated summa cum laude from Duke University in 1997 with a double bachelor’s degree — a B.A. in philosophy and a B.S. in electrical engineering. He won a Rhodes Scholarship and studied at Oriel College, Oxford, earning a B.A. in theology in 1999. He earned an M.A. in philosophy from the University of Notre Dame in 2000 and a J.D. magna cum laude from Harvard Law School in 2004, where he served as articles editor of the Harvard Law Review.
After law school, Sauer clerked for Judge J. Michael Luttig of the U.S. Court of Appeals for the Fourth Circuit (2004–2005) and for U.S. Supreme Court Justice Antonin Scalia (2005–2006). He practiced at Cooper & Kirk (2006–2008) before becoming an assistant U.S. attorney for the Eastern District of Missouri. He was an adjunct professor at Washington University in St. Louis School of Law (2011–2013). He was a partner at Clark & Sauer, LLC (2013–2015), then founded James Otis Law Group in 2015 — named for the colonial American lawyer who opposed British warrantless searches.
In January 2017, Missouri Attorney General Josh Hawley appointed Sauer as Solicitor General of Missouri, a position he held until 2023. As Missouri Solicitor General, he argued in defense of the state’s lethal injection protocol before the U.S. Supreme Court and challenged federal policies on COVID-19 vaccine mandates and social media content moderation.

Role and Function
The Solicitor General is the federal government’s chief advocate before the Supreme Court — sometimes called “the tenth justice” for the position’s influence on the Court’s docket and reasoning. The Solicitor General decides which cases the government will appeal, files amicus briefs in cases of federal interest, and personally argues the most consequential cases.
In this role, Sauer:
- Argues the administration’s most high-stakes Supreme Court cases, personally appearing before the justices in cases involving executive power, birthright citizenship, nationwide injunctions, and independent agency structure.
- Shapes the government’s legal strategy by deciding which lower court losses to appeal and how to frame constitutional arguments.
- Coordinates litigation across federal agencies, ensuring that all government legal positions align with the administration’s interpretation of executive authority.
- Advocates for expanded presidential power through litigation positions that consistently push the boundaries of executive authority.
CNN reported in May 2026 that Sauer “has locked arms with the 6-3 conservative supermajority in its drive to enhance executive power and overhaul voting rights and election law.” He has been described as the “legal architect of a reinvented executive branch” and is frequently mentioned as a potential Supreme Court nominee.

Documented Actions
Presidential Immunity — Trump v. United States (2024)
Before his confirmation, Sauer represented Donald Trump as private counsel in the landmark presidential immunity case. He argued before the Supreme Court that a former president has broad immunity from criminal prosecution for official acts. The Court ruled 6–3 in Trump’s favor, establishing that former presidents have presumptive immunity for official acts — a ruling that effectively ended the federal criminal case against Trump for his actions surrounding January 6, 2021.

Universal Injunctions — Trump v. CASA, Inc. (2025)
On May 15, 2025, Sauer argued before the Supreme Court that federal courts lack the authority to issue “universal” or “nationwide” injunctions that block executive orders beyond the specific plaintiffs in a lawsuit. On June 27, 2025, the Court ruled 6–3 in the administration’s favor, holding that universal injunctions “likely exceed the equitable authority that Congress has granted to federal courts.” The ruling — authored by Justice Barrett — partially stayed lower court orders blocking Trump’s birthright citizenship executive order.
During oral argument, Sauer stated that the executive branch “generally respect[s] circuit precedent, but not necessarily in every case” — a statement that alarmed legal observers as signaling the administration’s willingness to defy lower court rulings it disagrees with.

Birthright Citizenship — Trump v. Barbara (2026)
On April 1, 2026, Sauer argued before the Supreme Court that the Fourteenth Amendment’s Citizenship Clause does not confer citizenship on children born in the United States to parents who are unlawfully present or on temporary visas. He argued the Court faces a “new world” where “billions” are a plane ride away from obtaining U.S. citizenship for their children. Chief Justice John Roberts responded: “It’s a new world. It’s the same Constitution.” The case challenges more than a century of legal precedent established in United States v. Wong Kim Ark (1898). A decision is expected in summer 2026.

DOGE and Executive Office — May 2025
In May 2025, Sauer asked the Supreme Court to classify the Department of Government Efficiency (DOGE) as a “presidential advisory body” within the Executive Office of the President — an argument designed to shield DOGE from transparency requirements and legal challenges to its operations.

Independent Agencies — Trump v. Slaughter (Pending)
Sauer filed briefs arguing that the president has “conclusive and preclusive” power to remove heads of independent agencies at will, challenging the for-cause removal protections that have insulated agencies like the FTC, FCC, and CFPB from direct presidential control since the New Deal. In his brief, Sauer wrote: “The President must control all exercises of executive power.”

Controversies
Aggressive expansion of executive power: Legal scholars and former government lawyers have characterized Sauer’s litigation strategy as systematically dismantling judicial checks on presidential authority. By winning limits on nationwide injunctions, arguing for removal of independent agency heads, and seeking to reinterpret birthright citizenship, Sauer is reshaping the constitutional balance of power through litigation rather than legislation.
“Not necessarily in every case” — signaling defiance of courts: Sauer’s statement during Trump v. CASA oral arguments that the executive branch does not “necessarily in every case” respect circuit court precedent was widely interpreted as signaling the administration’s willingness to selectively ignore judicial rulings it disagrees with. This raised alarm among legal observers about the administration’s commitment to rule of law.

Supreme Court candidacy while arguing government cases: CNN reported that Sauer is “frequently mentioned as a possible Supreme Court nominee” and that Trump’s outside legal adviser Mike Davis said Sauer is “certainly at the top of my short list for the Supreme Court.” Critics have noted the structural tension between a Solicitor General who may be auditioning for a Court seat and his obligation to make disinterested legal arguments to the justices who would vote on his confirmation.

Tariff case loss and presidential fury: When Sauer lost a case challenging Trump’s tariff policy, Trump publicly blamed the justices at a White House news conference with Sauer present — an unusual display that blurred the line between the Solicitor General’s role as an officer of the Court and his role as an agent of the president’s political agenda.

Truth and Reconciliation Considerations
Sauer occupies a distinctive position in any future TRC examination. Unlike many administration officials whose accountability rests on policy decisions or personal conduct, Sauer’s accountability centers on his use of the legal system itself as a tool for restructuring American governance.
TRC Theme 1: Litigation as Constitutional Amendment
Sauer’s litigation strategy — eliminating nationwide injunctions, expanding presidential removal power, challenging birthright citizenship, shielding DOGE from oversight — collectively amounts to a restructuring of the constitutional separation of powers through judicial decisions rather than constitutional amendments. Each case standing alone is a legal argument; taken together, they represent a systematic campaign to concentrate power in the executive branch.
TRC questions for Sauer:
- What strategic framework guided the selection and sequencing of cases brought to the Supreme Court?
- Who in the White House or political operation directed or influenced the Solicitor General’s case selection?
- Were political considerations — including the president’s personal legal exposure — factored into litigation strategy decisions?
- Were there cases where career DOJ lawyers objected to the legal positions Sauer advanced?
TRC Theme 2: Presidential Immunity and Accountability
Sauer’s successful argument in Trump v. United States established a legal framework that shields former presidents from criminal prosecution for official acts. This ruling directly affected the accountability of the president Sauer subsequently went to work for — raising questions about whether the immunity argument was legal advocacy or self-interested shield-building.
TRC questions for Sauer:
- Was there any discussion, formal or informal, about a future government role for Sauer during or before the immunity case?
- Did the immunity ruling’s implications for January 6 accountability factor into the legal strategy?
- How does the immunity framework interact with the administration’s other litigation positions on executive power?
TRC Theme 3: Birthright Citizenship and the Fourteenth Amendment
The attempt to reinterpret birthright citizenship — a right established by the Fourteenth Amendment in response to the Dred Scott decision and confirmed by the Supreme Court in 1898 — represents an effort to narrow the scope of American citizenship through executive action rather than constitutional amendment.
TRC questions for Sauer:
- What internal legal analysis preceded the decision to challenge birthright citizenship?
- Were there dissenting views within the DOJ about the legal viability of this position?
- How does this litigation position interact with the administration’s broader immigration enforcement strategy?
Legal Status and Investigations
- No criminal charges
- No known ethics complaints
- Senate confirmation: Confirmed 52–45 on April 4, 2025

For Trump Supporters: Questions Worth Considering
The Solicitor General is the government’s top lawyer before the Supreme Court — a position that has historically been characterized by its commitment to legal accuracy and institutional credibility, even when that means acknowledging weaknesses in the government’s position. Past Solicitors General of both parties have occasionally conceded cases or modified arguments when the law did not support the government’s position, precisely because the Solicitor General’s credibility with the Court depends on intellectual honesty.
Here’s a question worth sitting with: Sauer is arguing that the president should have unilateral power to fire the heads of independent agencies, that courts cannot issue injunctions protecting anyone beyond named plaintiffs, that birthright citizenship can be redefined by executive order, and that DOGE should be shielded from transparency requirements. Each of these positions expands presidential power. If a future Democratic president inherited all of these legal precedents — the unlimited firing power, the inability of courts to issue broad injunctions against executive overreach, the power to redefine citizenship by executive order — would you be comfortable with that concentration of authority? Or does your support for these positions depend on who holds the office?
