His story
Stephen Miller became an American political advisor; Donald Trump’s deputy chief of staff for policy and homeland security adviser in January 2025; and on November 6, 2026 the White House chief of staff.
Miller grew up in Santa Monia, California and is the second of three children. He’s of Ashkenazi Jewish descent and went to Hebrew school at Beth Shir Shalom, where classmates thought of him as a contrarian (Uranus). He began identifying with ideologies associated with conservatism in the seventh grade.
In 1999, he began attending Santa Monica High School where he opposed the school’s chapter of the Chicano Student Movement of Aztlán and was described by the chapter founder as having taunted immigrants.
Miller began attending Duke University in 2003 to study political science. In 2004 he authored (Mercury) a column in the Duke Chronicle, Duke’s student newspaper titled ‘Miller Time’ in which he critiqued multiculturalism. His combative (Mars) debate strategy earned him a reputation for pugnacity (Mars is co-ruler of house 10).
After graduating in 2007, he worked as press secretary (Mercury) for US representatives Michele Bachmann and John Shadegg.
Following Donald Trump’s surprise victory in the 2016 presidential race, Miller assumed the role of presidential adviser and speechwriter (Mercury).
In January 2017 he was appointed White House Senior Policy Advisor and was an influential voice in shaping Trump’s immigration policies, often framing the issues as an effort to protect ‘Western civilisation’.
He’s credited with shaping the Department of Justice’s 2018 ‘Zero Tolerance’ policy at the US border, which called for the arrest of nearly every adult crossing into the US without legal documentation.
In January 2021 he left the White House at end of Trump’s term and founded America First Legal, a conservative legal advocacy organization.
In January 2025 when Trump returned to the White House Miller was appointed White House Deputy Chief of Staff for Policy and Homeland Security.
He moved from speechwriter to policy architect to a position of near‑total control over immigration enforcement; and helped to orchestrate Trump’s mass deportation drive, which has seen immigration enforcement agents flood communities across the country, increasingly targeting individuals with no or only minor criminal records.
He pushed for 3,000 arrests per day and in January 2026 his policy record directly tied him to the fatal Minnesota shootings and the subsequent popular backlash. (In his chart progressed Mars in house 8 [death] was square progressed Uranus.)
Stephen Miller is one of the most influential extremists (Uranus) in the Trump administration responsible for policies that separate families and ban Muslims.
His politics is described as far-right, anti-immigration and white nationalist.
In February 2020, he married Katie Waldman and they have four children.
On November 6. 2026 Trump named Miller as the White House chief of staff.
He’s tasked with overseeing White House staff and hiring, maintaining the president’s calendar, and advising the president on policy. The role largely controls information flows and is seen as the ‘gatekeeper’ to the presidency.
His chart progressed to November 6, 2026
Event markers are a progressed aspect to the Sun (his desire for power and significance) and a progressed aspect to the ruler of house 10 or the Midheaven (honor).
Progressed Sun at 10 Libra 54 in house 9 was sextile birth chart Moon at 11 Sagittarius 14 in house 11 (friends and hopes); and progressed Midheaven at 14 Sagittarius 22 in house 11 was conjunction progressed Uranus a 14 Sagittarius 42.
Progressed Venus at 14 Virgo 46 in house 8 was conjunction progressed Mars at 15 Virgo 15 the cusp ruler of house 10; and progressed ascendant at 4 Pisces 24 was trine progressed Pluto at 3 Scorpio 43 the cusp ruler of house 10 in house 9.
It’s likely that progressed Midheaven will be square progressed Mars for the duration of his tenure as White House chief of staff.
