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

“Nearly one in eight women in the United States will face this diagnosis,” said Wiles, who's the first woman to hold her position. “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.”

In a social media post, Trump described Wiles as “one of the strongest people I know” and said 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 on his Truth Social platform. “She will soon be better than ever!”

Within 20 minutes of Trump's post, Wiles was sitting alongside the president at a meeting of the Kennedy Center board of trustees. In opening remarks, Trump said Wiles had already begun treatment and described her diagnosis as a “minor difficulty" that she would overcome.

It comes as the Republican president confronts mounting challenges on global and national fronts, from the war in Iran and soaring oil prices to this fall’s midterm elections and Americans' concerns over affordability.

Wiles is a longtime Trump ally who rose from his campaign co-chair to his closest adviser and counsel. She spent decades as a lobbyist and political operative in Florida and led his 2016 effort in the state.

She mostly shuns the spotlight but drew attention in December with an unusually candid Vanity Fair interview in which she made critical remarks about Trump administration leaders including Vice President JD Vance and Attorney General Pam Bondi. Trump underscored his trust in Wiles in the aftermath, calling the interview a “hit piece” and describing Wiles as “fantastic.”

More than 300,000 women in the U.S. will be diagnosed with breast cancer this year, according to the American Cancer Society.

Treatment varies depending on how early the cancer is caught but usually involves either removing the tumor, followed by radiation, or removing the breast, what’s called a mastectomy. The cancer’s stage, subtype and genetic makeup can help determine if additional treatment of the original tumor is needed, or certain therapy to help prevent recurrence.

In his Monday post, Trump reiterated that Wiles is “tough and deeply committed to serving the American People.”

“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,” Trump said, referring to first lady Melania Trump.
