Former South Korean President Park Geun-hye was discharged from the hospital on Thursday. The 70-year-old says she's grateful to those who expressed concern about her health. Park, who was pardoned while serving a 22-year prison sentence for corruption, left Samsung Medical Center in Seoul. She had been receiving treatment for a chronic illness there since November. Before heading home, Park is expected to visit the grave of her late father, former President Park Chung-hee, at Seoul National Cemetery.
