Who Is Stephen Miller?

Stephen Miller, 41, has been one of Trump's closest political and policy advisers since the 2016 presidential campaign. He most recently served as deputy chief of staff for policy and homeland security adviser in the administration.

Miller is regarded as a key architect of Trump's hard-line immigration policies, including the administration's efforts to expand deportations and tighten border controls. He played a major role in shaping the immigration agenda during Trump's first term and returned to a senior position in the White House after the president's comeback in 2024.

After leaving the White House in 2021, Miller founded America First Legal, a conservative legal organisation that pursued legal challenges aligned with Trump's political agenda.

What Happened to Susie Wiles?

Susie Wiles, who served as Trump's chief of staff, is stepping down from the position and will move to the president's political operation, according to Trump's announcement.

Wiles made history as the first woman to serve as White House chief of staff. She was also a top figure in Trump's political comeback and served as a central organiser of his 2024 presidential campaign.
