White House Chief of Staff Susie Wiles will undergo treatment for early-stage breast cancer, according to an announcement from Donald Trump.

The president shared the news in a post on Truth Social, praising Wiles as a key figure inside his administration and expressing confidence in her recovery.

“Susie is an incredible Chief of Staff, a great person, and one of the strongest people,” Trump wrote. “She has a fantastic medical team, and her prognosis is excellent.”

Trump said Wiles plans to continue working while receiving treatment and will remain heavily involved in White House operations.

According to the president, she will be “spending virtually full time at the White House” as she undergoes care.

Trump also emphasized her determination to stay engaged in her role.

“Susie, as one of my closest and most important advisors, is tough and deeply committed to serving the American People,” he wrote. “She will soon be better than ever.”

Trump added that he and Melania Trump are supporting Wiles during her treatment.

“Melania and I are with her in every way,” the president said.

Wiles, 68, holds a historic position inside the administration. She is the first woman to serve as White House chief of staff since the role was formally established during the presidency of Dwight D. Eisenhower in the 1950s.

A veteran political strategist, Wiles has been involved in Republican politics for decades.

Her career began in the late 1970s and included a stint in the administration of Ronald Reagan during the early 1980s.

In the years that followed, she built a powerful reputation as a political consultant and lobbyist in Florida, where she eventually became a key figure in Republican campaign strategy.

Wiles first entered Trump’s inner circle during his 2016 presidential campaign and later played a major role in managing his political operations in Florida.

She rose to national prominence during Trump’s 2024 campaign, which she co-managed and helped guide back to the White House.

Wiles also remained one of the few advisers who stayed loyal to Trump after his 2020 election defeat and the political fallout surrounding the January 6 United States Capitol attack.

Since becoming chief of staff, Wiles has gained a reputation as a disciplined and discreet operator capable of managing the often turbulent environment inside the West Wing.

Trump has had multiple chiefs of staff during his time in office, making Wiles the fifth person to hold the position during the five years he has served as president.

Despite the turnover that has characterized the role, Wiles is widely viewed as one of the most effective figures to manage Trump’s White House.

Outside of politics, Wiles also comes from a well-known family.

She is the daughter of Pat Summerall, the legendary NFL player turned sportscaster who became one of the most recognizable voices in football broadcasting.

While the diagnosis marks a personal challenge, Trump’s announcement stressed that Wiles plans to remain deeply involved in the administration’s work as she begins treatment.

“She loves the job she’s doing,” Trump wrote, “and she’s going to keep doing it.”
