WASHINGTON (AP) — Defense Secretary Lloyd Austin has undergone a medical procedure at Walter Reed National Military Medical Center and has resumed duty after temporarily transferring power. He is continuing to deal with bladder issues that arose in December following his treatment for prostate cancer. The Pentagon says the procedure Friday was successful, elective and minimally invasive, “is not related to his cancer diagnosis and has had no effect on his excellent cancer prognosis.” Austin has returned home, and the Pentagon says no changes in his official schedule are anticipated, including his participation in Memorial Day events.
