White House Chief of Staff Susie Wiles has been diagnosed with early-stage breast cancer, President Donald Trump announced Monday via Truth Social. The president described Wiles as a “tough and deeply committed” leader who plans to undergo treatment immediately while maintaining her responsibilities at the White House.

“Susie Wiles is an incredible Chief of Staff, a great person, and one of the strongest people I know,” Trump wrote. “She has a fantastic medical team, and her prognosis is excellent! During the treatment period, she will be spending virtually full-time at the White House, which makes me, as President, very happy!"

Trump praised Wiles for her dedication to public service, highlighting her ability to continue leading while addressing a personal health challenge. “Her strength and her commitment to continue doing the job she loves, and does so well, while undergoing treatment, tells you everything you need to know about her,” he said. “She will soon be better than ever! Melania and I are with her in every way, and we look forward to working with Susie on the many big and wonderful things that are happening for the benefit of our country!”

Wiles is known for her decisive leadership style and long career in conservative politics. She has previously worked with prominent Republican figures in Florida, including Sen. Rick Scott and Gov. Ron DeSantis, and has been a key advisor to President Trump for multiple years.

The announcement comes as Wiles prepares to balance her treatment with continued oversight of White House operations, reflecting her reputation as a committed and high-performing chief of staff.
