Additional archived dossier material
Government career
Miller served as a senior adviser during the first Trump administration, where immigration and domestic-policy strategy were central parts of his portfolio.
White House records list him in the second administration as an assistant to the president, deputy chief of staff for policy and homeland security adviser.
America First Legal
After the first administration, Miller co-founded America First Legal, a conservative legal-advocacy organization that uses litigation, administrative complaints and public-records work to challenge government and private-sector policies.
CPI says it provided incubation support to help launch AFL, making the organization part of the broader outside-government infrastructure documented elsewhere on the site.
Why the personnel bridge matters
Miller's path shows how an official can move from government into an outside legal institution and later return to a senior policy role.
That creates continuity of people, ideas and relationships across administrations without proving that the outside organization controls later government decisions.
Evidence limits
AFL litigation positions and White House policies may overlap, but overlap alone does not establish that AFL authored a later government policy.
Miller's formal White House role should be distinguished from the independent legal status of AFL.
Overview
Stephen Miller served as a senior adviser in the first Trump administration, helped establish America First Legal in 2021, and returned to the White House in 2025 in a senior policy and homeland-security role.
White House career
America First Legal's official leadership biography identifies Miller as a senior adviser in the first Trump administration and a deputy chief of staff for policy and homeland security adviser beginning in January 2025.[1]
Those are roles within government; the source does not prove that a private organization directs White House decisions.[1]
America First Legal
Miller was a co-founder of America First Legal, a conservative legal-advocacy organization launched after the first Trump term. AFL's leadership page now names Gene Hamilton as its president and co-founder, and Miller as co-founder.[1]
The co-founder role is a documented institutional link; the public page does not establish Miller's operational involvement in every lawsuit AFL pursues.[1]
Why this connection matters
The sequence of federal service, outside legal advocacy, then return to government illustrates a personnel pathway that can be traced from individual biographies. Tracing a pathway is not the same as proving unlawful coordination.[1]
