Secretary of Defense Lloyd Austin admitted he was wrong to hide his cancer diagnosis and subsequent hospitalization, though he maintained he never directed his staff to hide his trip to Walter Reed National Military Medical Center.

The secretary was diagnosed with prostate cancer in early December, had surgery to treat it on Dec. 22, 2023, and was hospitalized with complications on Jan. 1. He stayed in the hospital for two weeks. He briefly gave up some of his authorities to Deputy Secretary of Defense Kathleen Hicks, while the White House, Congress, and the public were not notified of his hospitalization for days.
