U.S. Former President Joe Biden’s son Hunter Biden said Friday that his father’s prostate cancer has spread to his bones, describing the condition as painful and debilitating. “He’s really struggling,” Hunter Biden told the BBC in a televised interview. “It’s very painful, and it’s very debilitating in many respects, but he’s still out there, and he’s still doing his thing,” Hunter Biden said. Former first lady Jill Biden said in June that Joe Biden would likely live with cancer for the rest of his life because the disease had spread to his bones. Hunter Biden became emotional while discussing his father, calling him “our rock” and saying Biden had supported each of his children throughout their lives.
