Former President Joe Biden’s son Hunter Biden said Friday in a wide-ranging interview about the family that his father’s prostate cancer has recently spread further and “it’s not good.”

“The cancer has spread, it’s metastasized into his bones and further,” Hunter said in an interview with BBC’s Paddy O’Connell. “It’s very painful, um, and it’s very debilitating in many respects. But he’s still out there, he’s still doing his thing, he so believes in this country, and as long as he’s alive, I promise you he’s going to continue to fight.”
