White House chief of staff Susie Wiles has breast cancer but will keep working through treatment - AP News

White House chief of staff Susie Wiles has been diagnosed with breast cancer but plans to continue working while undergoing treatment. Wiles, who served as Trump's campaign manager during his successful 2024 presidential run, became the first woman to hold the chief of staff position when Trump took office in January 2025. The announcement raises questions about potential impacts on White House operations, as the chief of staff role involves managing the president's schedule, coordinating policy implementation, and serving as a key gatekeeper to the Oval Office. Wiles has been a longtime Trump confidant and is considered one of his most trusted advisers, making her continued presence crucial to the administration's functioning. The White House has indicated that her treatment schedule will be accommodated while she maintains her duties.
