Stephen Miller has risen to be one of the most influential figures in Donald Trump’s second term in the White House. Initially dismissed by senior military leaders, he has now become the central architect behind the administration’s stringent immigration policies.
RadarOnline.com highlights Miller’s transformation as detailed in the book Regime Change: Inside the Imperial Presidency of Donald Trump, authored by New York Times reporters Maggie Haberman and Jonathan Swan.
Based on extensive interviews with anonymous officials, the book explores how Trump, at 80, has strengthened executive power in his second term. It also details how Miller’s impact grew significantly after playing a less prominent role in Trump’s first presidency.
A source familiar with the White House dynamics stated, “Stephen Miller has become the undisputed enforcer of the president’s immigration agenda. Few major domestic policy decisions move forward without his approval, as even those who underestimated him now acknowledge.”
Another insider noted, “His authority has grown to a level that surprises even longtime Trump allies. He has positioned himself at the center of the administration’s most controversial priorities.”
The book portrays Trump as the “most powerful president of our lifetimes,” describing him as a leader driven by “grievances and instincts,” often disregarding established political norms. It also narrates an unusual incident where Trump was found using super glue to decorate parts of the White House.
Authors Haberman and Swan have reached out to individuals mentioned in the book, offering them a chance to share their perspectives. Their account relies on interviews conducted under anonymity due to the sensitive nature of the discussions and decision-making described.
According to the book, Miller was a prominent figure in Trump’s immigration crackdown during his first term. Despite his visibility, in his early 30s, he was reportedly “easily dismissed” by senior military leaders, which limited his influence on broader government policies.
This scenario reportedly changed dramatically during Trump’s second term. Although Miller’s official roles as deputy chief of staff for policy and homeland security adviser seemed modest, the authors of Regime Change claim they masked the extensive reach of his influence within the White House.
The book notes that Miller’s responsibilities spanned much of the federal government. He was involved in overseeing executive orders, recruiting the lawyers to draft them, and spearheading the Department of Homeland Security’s mass deportation strategy, including advocating for the deployment of US troops in American cities.
The book also alleges that Miller was often blunt with subordinates. During one meeting on accelerating deportations, it claims he threatened to remove the entire leadership of Immigration and Customs Enforcement if results did not improve fast enough.
The authors suggest Miller often presented his policy suggestions as direct requests from Trump while being careful not to express personal views in the president’s presence. This approach reportedly allowed him to expand his authority and reinforce the belief that his directives had the president’s full support.
Miller currently serves as the White House Deputy Chief of Staff for Policy and the United States Homeland Security Advisor. Known as one of Trump’s immigration “attack dogs,” he is a key architect of the administration’s hardline immigration agenda and aggressive deportation policies.
Miller is credited with driving the administration’s strict border policies, including mass detention, deportation directives, the travel ban, and the family separation policy. He is recognized for quickly turning Trump’s political instincts into actionable orders.
During Trump’s initial term, he started as Director of Speechwriting and has consistently helped craft many of Trump’s significant speeches and public addresses. A source stated, “Miller has carved himself out a place as a conservative firebrand, and his influence now extends far beyond the border into broad domestic and foreign policy areas.”
