White House Chief of Staff Susie Wiles has been diagnosed with “early-stage breast cancer” but is remaining at work while undergoing treatment, President Donald Trump announced Monday.
Wiles, 68, “chose to take on this challenge IMMEDIATELY rather than wait,” Trump said in a Truth Social post revealing the diagnosis.
She has an “excellent” prognosis and will “spend virtually all of her time in the White House,” Trump said in the post.
“Her strength and commitment to continuing to do the job she loves and does so well during treatment tells you everything you need to know about her,” he said.
The White House did not immediately respond to CNBC’s request for additional information about Wiles.
She appeared alongside Trump at the White House on Monday afternoon during a board meeting of the John F. Kennedy Center for the Performing Arts. The board, filled with Trump representatives including Wiles, had met to vote on plans to close the center for renovations starting July 6, The New York Times reported.
Trump said at the event that Wiles was dealing with a “minor issue” and reiterated that she would take care of it “immediately.”
Wiles said in an X post later Monday that she received her diagnosis last week and confirmed that she would continue to serve in the White House.
“Nearly one in eight women in the United States face this diagnosis. Every day, these women continue to care for their families, go to work, and serve their communities with strength and determination. I join their ranks now,” Wiles said in the post.
“I am grateful to have an excellent team of doctors who caught the cancer early and are guiding my treatment, and I am encouraged by a very good prognosis,” she said in her post.
Wiles led Trump’s victorious 2024 presidential campaign and wielded major influence in his second administration.
While Wiles is often seen alongside Trump at public events, he rarely speaks on camera or grants official interviews. However, in 2025, she participated in a series of interviews with Vanity Fair that revealed strikingly blunt assessments of Trump and his top aides.
She told the medium, among other things, that Trump had “the personality of an alcoholic” and that as president he committed legal “retaliation” against his enemies.
After the interviews were published in December, Trump said he stood by Wiles, and a number of senior administration officials jumped to her defense while attacking Vanity Fair. Wiles himself described the articles as a “hit piece”.
