Stephen Miller’s growing influence in Donald Trump’s second term illustrates how political power operates through bureaucracy as much as legislation.
His approach is not simply about speeches or executive orders. It involves changing how government rules are interpreted, directing agencies to enforce those interpretations, and using administrative power to reshape policy.
The 2026 midterm elections have made that strategy more consequential. During Trump’s first administration, Miller helped drive the expansion of the Public Charge rule, which broadened the circumstances in which immigrants could be deemed likely to depend on government assistance.

The policy faced legal challenges and was later reversed, but uncertainty discouraged some immigrant families from seeking public benefits. It demonstrated how administrative rules can influence decisions before courts deliver a final judgment.
The bureaucracy itself can become an instrument of deterrence. That lesson is relevant to the second term, where Miller has played a central role in immigration enforcement and domestic priorities.
His influence increased on November 6, when Trump named him White House chief of staff, replacing Susie Wiles. The appointment followed Democratic midterm victories and suggests Trump may respond to electoral setbacks by consolidating authority around one of his most hard-line advisers.
Russell Vought’s position at the Office of Management and Budget adds another dimension. Miller can shape policy and legal arguments, while Vought oversees federal budget execution and influences how agencies distribute resources.
Reuters reported before the election that the White House had prepared executive actions on immigration, tariffs, housing and federal spending in anticipation of a Democratic takeover.
Officials were examining how to advance priorities using funds already appropriated by Congress and give political appointees greater influence over federal grants. The results have changed Washington.
Democrats won control of both chambers, gaining power to investigate the administration, scrutinize spending, block legislation and reject executive and judicial nominees. Voters were motivated partly by frustration over living costs, inflation and the Iran war.
The result is a major rebuke to Trump, but it does not remove his executive authority. That is the central tension. A Democratic Congress can hold hearings, issue subpoenas, demand documents and challenge policies through legislation and oversight.
Yet Trump retains the veto, control over executive agencies and significant authority over immigration and foreign policy. The White House may therefore rely more heavily on unilateral action, administrative reinterpretation and litigation rather than compromise.
For civil liberties advocates, the concern is that broad national-security definitions or restrictive funding rules could pressure nonprofit organizations, universities and other institutions critical of the administration.
Such measures would face constitutional and statutory limits. Congress controls appropriations, and courts can review unlawful executive action. But prolonged legal battles can impose costs even when policies are eventually blocked.
Miller’s worldview connects immigration to globalization and wages. He argues employers benefit from lower-cost labor, while critics note immigration supports growth, entrepreneurship and essential industries.
The dispute is therefore not only about border enforcement, but about who benefits from the American economic model. The midterms have given Democrats tools to resist.
Miller’s promotion suggests Trump intends to push forward regardless. The coming confrontation will test whether congressional oversight and judicial independence can restrain an administration determined to govern through executive power.
