On April 21, 2026, Politico reporter Nick Niedzwiadek reported that Keith Sonderling — elevated the previous day to acting Labor Secretary after Lori Chavez-DeRemer's resignation — had effectively been running the Department of Labor throughout Chavez-DeRemer's tenure, with the White House and business lobby having lobbied for his deputy appointment precisely to provide that redundancy.
The "Shadow Secretary" Thesis
Multiple sources inside DOL and across the Republican labor-policy network told Politico that Sonderling, together with senior counselor Courtney Walter (another Trump first-term DOL alumnus), had run day-to-day operations while Chavez-DeRemer toured all 50 states during her first year.
> "Keith and Courtney have run it the entire time." — Senior DOL appointee, quoted anonymously in Politico.
> "He is really the pivot point of all labor and workforce policy for this administration." — Republican operative close to the administration.
> "His job title considerably understates his importance on labor and employment matters to the administration." — Roger King, senior labor counsel for the CHRO Association.
Business groups had lobbied for Sonderling's deputy appointment after being "caught off-guard" by Trump's selection of Chavez-DeRemer, a union-friendly former House member endorsed by Teamsters president Sean O'Brien at the 2024 RNC. Sonderling was confirmed as deputy on March 12, 2025 — two days after Chavez-DeRemer.
Sonderling's Cross-Agency Footprint
Beyond DOL, Sonderling serves simultaneously as:
The Indefinite Acting Pathway
The Vacancies Reform Act normally limits how long executive officials can fill acting roles. However, a separate statute permits the deputy Labor Secretary to serve acting duties "until a successor is appointed" — a pathway the Biden administration used to keep Julie Su as acting Labor Secretary for the remainder of the term after her Senate nomination stalled. A 2023 GAO report confirmed that legal interpretation.
> "If Trump is happy with Sonderling … even if there is no nomination, he could be acting labor secretary the rest of the term." — Thomas Berry, Cato Institute.
A White House official told Politico the president will decide on the Labor nomination "in due time." Sonderling declined to be interviewed.
Background
Sonderling, 43, a Florida Republican and former Gunster partner:
In 2019, Sonderling authored the DOL opinion letter concluding gig workers were independent contractors under the FLSA — the letter was withdrawn by the Biden administration in 2021 and reinstated in May 2025.
Progressive labor consultant Judy Conti told Politico: "I've always known him to be a straight shooter and accessible. We disagree, but it's always in a respectful fashion."
Financial Disclosure Pattern: The Management-Defense Bar Pipeline
Sonderling's January 2025 Form 278e financial disclosure, as published by ProPublica, shows a profile distinct from the Blue Owl / private-credit conflicts documented in other Trump Cabinet appointees. His personal holdings are modest, diversified, and concentrated in index funds and retirement accounts — no Blue Owl, no BDC, no private credit, no detention or surveillance equity. A bulk divestiture of individual stocks occurred March 28, 2025.
What the disclosure documents instead is a direct pipeline from the management-side labor-and-employment defense bar into the top of DOL:
Gunster, Yoakley & Stewart PA. Sonderling was a partner at Gunster — one of Florida's oldest and largest law firms, with a major management-side labor and employment practice — before entering government. The firm represents employers in disputes against the Department of Labor's enforcement arms. His $500K–$1M Gunster 401(k) remains intact.
Constangy, Brooks, Smith & Prophete, LLP — consulting for Walmart. Between leaving the EEOC in 2024 and being announced as Deputy Secretary nominee on January 15, 2025, Sonderling operated a sole proprietorship, "KS Firm," from November 2024 to January 2025. During that window he earned $50,490 in consulting fees. The disclosed compensation source: Constangy, Brooks, Smith & Prophete — a national management-side labor-and-employment defense firm. The disclosed client of those services: Walmart. Walmart is among the largest single targets of DOL Wage and Hour enforcement, OSHA investigations, and NLRB proceedings in the United States. Sonderling was paid to consult for Walmart, via Constangy, in the two months before his Senate nomination to oversee the agencies that enforce labor law against Walmart.
Spouse's employer: American Forest & Paper Association (AF&PA). Sonderling's spouse draws salary and bonus from AF&PA, a trade association whose core lobbying portfolio includes DOL's OSHA paper-mill safety standards and forest-products wage-and-hour matters. No stock held — the conflict is employment-based, not equity-based.
Trump Vance 2025 Transition volunteer. Sonderling served on the Trump transition team from September 2024 to January 2025 — overlapping the Constangy/Walmart consulting engagement.
The pattern is not the same as the Blue Owl beneficiary network. It is the recurring pattern of the management-side labor-defense bar placing its alumni in DOL's enforcement leadership, one appointment at a time, with a recent-client footprint at the specific firms DOL enforces against. Walmart is a named client two months before nomination. His ethics agreement would ordinarily require recusal from Walmart-specific matters for one year under standard Trump-administration ethics pledges, but the broader enforcement portfolio — Wage & Hour rulemaking, OSHA standard-setting, gig-economy classification — lies outside any single-firm recusal.
Significance
The Politico reporting and the financial disclosure together expose four patterns:
1. Figurehead Cabinet, operational deputy. Chavez-DeRemer was the public Cabinet face; business groups secured the operational control at the deputy level. Her misconduct scandal accelerated but did not change Sonderling's operational primacy.
2. The deputy-as-permanent-acting workaround. The statutory pathway that let Julie Su hold acting duties for years under Biden now enables Sonderling to serve indefinitely under Trump — avoiding a confirmation fight for the full Cabinet role while preserving operational continuity.
3. Cross-agency policy consolidation. A single deputy-level appointee runs DOL, acts as IMLS head, scouts NLRB nominees, and functions as the administration's workplace-policy hub. The influence network is denser than any single confirmation hearing captured.
4. Management-defense bar pipeline into enforcement leadership. The documented consulting engagement for Walmart — routed through Constangy, Brooks, Smith & Prophete in the two months before nomination — is the clearest single-client conflict in the record. The pattern is not equity-based corruption (as with Blue Owl beneficiaries) but client-based: moving from defending employers against DOL enforcement to setting DOL enforcement priorities, with a specific named client still unresolved.
The Labor Department has been a recurring headache for Trump administrations: Andrew Puzder (withdrawn, 2017, domestic-abuse allegations he denied), Alexander Acosta (resigned 2019 over his Epstein prosecution as U.S. Attorney), and now Chavez-DeRemer. Sonderling represents the institution's pivot from public-facing Cabinet turnover to embedded operational control.
