President Trump on Monday announced that Chief of Staff Susie Wiles has been diagnosed with early stage breast cancer. “Susie Wiles is an incredible Chief of Staff, a great person, and one of the strongest people I know but, unfortunately, she has been diagnosed with early stage breast cancer, and has decided to take on this challenge, IMMEDIATELY, as opposed to waiting. 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 said. “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. Susie, as one of my closest and most important advisors, is tough and deeply committed to serving the American People. 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!” he added. Full post: Axios shared further: Wiles takes part in nearly every major decision Trump has made as president and also assembled his White House staff that’s deeply loyal to both the president and her. “This past week, I was diagnosed with breast cancer,” Wiles said in a written statement. “Nearly one in eight women in the United States will face this diagnosis. Every day, these women continue to raise their families, go to work, and serve their communities with strength and determination. I now join their ranks.” Wiles said she was “grateful to have an outstanding team of doctors who detected the cancer early and are guiding my care, and I am encouraged by a strong prognosis. I am also deeply thankful for the support and encouragement of President Trump as I undergo treatment and continue serving in my role as White House Chief of Staff.” White House chief of staff Susie Wiles diagnosed with breast cancer, Trump announces https://t.co/5ghCBJsKXO pic.twitter.com/a4HSMyaTBe — New York Post (@nypost) March 16, 2026 More from The Washington Post: Wiles, a longtime Florida-based political strategist, helped Trump win the state in 2016, a key pickup in his successful bid for the White House that year. After Trump lost the 2020 election and seethed about his diminished political fortunes, Wiles managed his victorious 2024 presidential campaign and has served as his chief of staff since January 2025. Wiles has described her role as empowering Trump’s agenda, rather than serving as a check on his impulses, a break from some past chiefs of staff who have said that their most important role was saying no to the nation’s leader. She has also described Trump as having “an alcoholic’s personality,” saying he “operates [with] a view that there’s nothing he can’t do. Nothing, zero, nothing,” among several comments that were published in a pair of Vanity Fair articles that drew national attention last year. White House officials quickly defended her, and Wiles said that the articles took her comments out of context. Trump said that she had done a “fantastic job” and would remain his chief of staff. Beyond Trump, Wiles has advised or managed the political campaigns of other prominent Republicans, including Florida Gov. Ron DeSantis and Sen. Rick Scott of Florida. She also served as a lobbyist at Ballard Partners, an influential firm that has represented many major corporations with business before the Trump administration. Wiles left Ballard Partners in 2019, citing health issues. She is a daughter of Pat Summerall, a former football player and TV announcer.
