U.S. President Donald Trump points something out to his Chief of Staff Susie Wiles on the South Lawn of the White House in Washington, D.C., U.S., January 6, 2026.
Susie Wiles' cancer diagnosis
In mid-March, Wiles announced that she had been diagnosed with breast cancer, which she said had been caught in the early stages, according to NBC News.
President Trump also posted about Wiles' diagnosis on social media, saying that she would receive treatment immediately. He called Wiles "an incredible Chief of Staff, a great person, and one of the strongest people I know" in a post on Truth Social at the time.
"During the treatment period, she will be spending virtually full time at the White House, which makes me, as President, very happy! 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," Trump added in the post.
Despite the diagnosis, Wiles remained a fixture at Trump's side and also traveled with him on an official trip to Dallas, Texas, in September, according to CBS News.
Wiles thanked President Trump for his "unwavering support", adding that she was "deeply grateful and will continue to work to advance his America First Agenda."
What Wiles said after her ouster
Speaking after her ouster as the White House chief of staff, Wiles said working in the role had been "the honor of a lifetime."
She added: "I’m so proud to have been a part of what we’ve accomplished together, from securing our border and cutting taxes to strengthening our economy and putting America first."
