@foxnews: "My life was about more than my disease." Susie Wiles opens up about undergoing chemotherapy while serving as President Trump's chief of staff, revealing how work gave her a sense of purpose as treatment tested her stamina, mobility and focus. "Work did not make the cancer disappear from my mind. However, it reminded me that I was still myself." Some days, simply getting out of bed and making it to work was a test. But Wiles says she was determined not to let cancer make her world smaller and kept focusing on the job in front of her.
