# DHS Component Tree An ASCII-art map of the **Department of Homeland Security** one level deeper than the [[Executive Branch Org Chart]] shows it — the eight operational components with their current heads and major sub-units, plus the headquarters and oversight tiers. DHS is the department behind the immigration crackdown, and the structural story the tree tells is churn: **as of July 28, 2026, half of the eight operational components are run by acting officials**, and the department is on its second Secretary of the term. Leadership reflects the Second Trump administration as of that date. This is the structural companion to the [[Department of Homeland Security]] prose page (which carries the capture analysis) and a sibling of the [[Combatant Commands Map]] and [[Intelligence Community Tree]] in the map series. > [!note] How to read this chart > **★** marks a Senate-confirmed head. **(acting)** marks an official serving without confirmation for that seat. Sub-units are institutions, not named individuals. Bracketed notes flag pending nominations and mid-term changes with dates. The Secret Service directorship requires no Senate confirmation, so it carries neither mark. ``` U.S. DEPARTMENT OF HOMELAND SECURITY — COMPONENTS & LEADERSHIP (as of July 28, 2026) │ Created 2003 from 22 merged agencies · ~260,000 employees · third-largest department │ ★ = Senate-confirmed head (acting) = serving without confirmation for the seat │ ■ SECRETARY OF HOMELAND SECURITY ★ — Markwayne Mullin [sworn Mar 24, 2026; replaced K.

The confirmed heads: [[Markwayne Mullin]] (Secretary, 54–45, sworn March 24, 2026, replacing [[Kristi Noem]], who moved to the "Special Envoy for the Shield of the Americas" role), [[Troy Edgar]] (Deputy Secretary), [[Rodney Scott]] (CBP), [[Joseph Edlow]] (USCIS, confirmed July 15, 2025), and Adm. [[Kevin Lunday]] (Coast Guard, installed as 28th Commandant January 15, 2026, after roughly a year as acting following the January 2025 firing of Adm. Linda Fagan). - **ICE — the revolving door runs through the detention industry.** Acting director [[Todd Lyons]] resigned effective end of May 2026 after a year of controversy over enforcement tactics; the agency is now led in an acting capacity by [[David Venturella]], a longtime ICE official who spent the intervening years as an executive of the GEO Group, the private prison and detention contractor that holds major ICE contracts. [[Lance Schroyer]] — a former Oklahoma state trooper and senior adviser to Mullin — was nominated June 27, 2026; if confirmed he would be the first Senate-confirmed ICE director in more than a decade. - **FEMA — the nominee is the official fired for defending the agency.** Robert Fenton, the career official who has repeatedly served as acting administrator, took over May 12, 2026. The pending nominee, Cameron Hamilton, was fired as acting administrator in May 2025 one day after testifying to Congress that FEMA should not be eliminated; his nomination to lead the same agency advanced to the Senate floor in July 2026. - **CISA has had no confirmed director the entire term.** Sean Plankey's nomination collapsed — a hold by Sen. Rick Scott, concerns over shipbuilding-contract involvement, removal from his DHS advisory post in March 2026 — and he withdrew in April 2026 with no replacement nominee announced. Nick Andersen is the latest acting director, following Madhu Gottumukkala's departure. - **TSA** has been led by senior official Ha Nguyen McNeill without confirmation; David Cummins's nomination got its Commerce Committee hearing July 16, 2026. - **[[Sean Curran]]** (Secret Service) has led since January 22, 2025; the directorship is a presidential appointment requiring no Senate vote. Structural notes: - The **oversight tier was hollowed out early**: the Office for Civil Rights and Civil Liberties, the CIS Ombudsman, and the Office of the Immigration Detention Ombudsman — the three offices that field complaints about enforcement and detention — had their staffs largely cut in March 2025. The offices remain statutory, so they appear in the tree with bracketed flags rather than being omitted. - **Two DHS components are Intelligence Community elements** — the Office of Intelligence & Analysis and Coast Guard Intelligence. See the [[Intelligence Community Tree]] for how they sit in the 18-element federation. - The Coast Guard's placement is the department's oddest feature: an **armed force inside a civilian law-enforcement department**, transferable to the Navy in wartime. ## See also - [[Department of Homeland Security]] — the prose page: leadership transition, the capture lens, Project 2025 targeting - [[Executive Branch Org Chart]] — the whole-branch map this tree zooms into - [[Intelligence Community Tree]] · [[Combatant Commands Map]] — sibling maps in the series - [[CBP]] · [[ICE]] · [[USCIS]] · [[TSA]] · [[FEMA]] · [[CISA]] · [[United States Secret Service]] · [[United States Coast Guard]] — component pages - [[US Immigration Timeline]] — the enforcement program this machinery executes - [[Trump 2.0 Cabinet Hub]] · [[Federal Agencies Hub]]
