'Voices in head said to kill Trump': Man with firearms arrested near White House

Stephen Miller, a key figure in former President Donald Trump's administration, has been appointed as the new White House Chief of Staff. Miller, 41, is known for his role in shaping Trump's hardline immigration policies and will take over from Susie Wiles, who was the first woman to hold the position during Trump's second presidency.

Miller's association with Trump began during the 2016 presidential campaign, where he worked as a speechwriter before becoming a senior adviser in Trump's first administration from 2017 to 2021. He continued to influence Trump's policies after Trump returned to the White House in 2025, serving as deputy chief of staff and homeland security adviser.

Miller's most prominent role was in immigration, where he advocated for stricter controls and played a significant part in turning Trump's campaign promises into government policy. He pushed for a daily target of 3,000 arrests by Immigration and Customs Enforcement (ICE) and encouraged operations at Home Depot outlets. He also backed an end to birthright citizenship and targeted foreign nationals traveling to the US for birth tourism.

However, Miller's immigration crackdown has faced political opposition. A Reuters/Ipsos survey found that 54% of respondents disapproved of the enforcement drive, while 36% approved. Democrats plan to scrutinize Miller's role in policy as Democrats are set to take control of Congress.

Beyond immigration, Miller has also been involved in reducing the federal workforce, disputes with universities over diversity programs, and expanding presidential authority. He has defended US military operations against suspected drug-smuggling vessels and backed American and Israeli military action against Iran. Miller has also refused to rule out military action to acquire Greenland.

Miller's appointment as Chief of Staff comes at a time when Trump faces potential congressional investigations into his administration and policies. Democrats, including incoming House Speaker Hakeem Jeffries and House Oversight Committee Chairman Robert Garcia, have warned that Miller could be targeted for scrutiny over the administration's immigration operations.
