White House chief of staff Susie Wiles is leaving her post, according to President Trump. Trump said Wiles will move over to his political operation, and that Stephen Miller — until now deputy chief of staff — will succeed her. The president described Miller as "one of my most trusted advisors." The chief of staff role sits at the apex of the West Wing, running the president's schedule, staffing, and access to the Oval Office — a job whose occupant shapes the day-to-day policy agenda. Changes in the position tend to draw attention well beyond Washington, and this one lands on an administration still carrying two defining, unresolved files: tariffs and the war with Iran.

Bloomberg reported that Wiles resigned on Thursday night, suggesting the impetus for the change may have come from her rather than from Trump.

Miller is best known as a hardline hawk on immigration. He became less prominent after the immigration roundups in Minnesota. More consequentially, he has been one of the most forceful public defenders of Trump's 2026 war against Iran.

In April, Miller argued that the American blockade could continue indefinitely if Iran refused a deal. He also threatened the potential destruction of Iranian energy infrastructure, although he characterized that as a last resort.

The original report suggested the appointment could be an early signal that Trump has no plans to make peace or to dial down tariffs, and may instead escalate on both fronts in order to reframe his legacy as a leader who made tough choices for the long term. It also cautioned that, with little reporting on Miller's private stance, he may simply be repeating standard White House talking points.

Either way, Miller's move from deputy chief of staff to the top staff position increases his potential influence over which recommendations reach the president and how decisions are implemented. In almost all respects, he is more ideological than Wiles.

Update: Maggie Haberman — described by the report as highly credible — wrote: "Miller’s pitch for the job, according to people who heard it, was that the president needed to wind down the Iran war, a conflict that the president’s core supporters viewed as a betrayal."

The report characterized that development as a positive sign toward a reopening of the Strait of Hormuz. The waterway is the world's most important chokepoint for seaborne oil, which is why any movement toward reopening it carries weight for global energy supply regardless of where the broader conflict stands.

From here, the concrete markers to watch are whether Miller's reported pitch to wind down the war translates into visible movement on the blockade and the strait, and how Wiles' transition into Trump's political operation is formalized.
