Leaders from across the political spectrum — including Trump, Obama, and Rubio — are offering prayers and well wishes after Joe Biden was diagnosed with an aggressive form of prostate cancer that has spread to his bones.

Former President Bill Clinton, who was diagnosed with skin cancer at the end of his presidency in 2001, posted on X: “My friend Joe Biden’s always been a fighter. Hillary and I are rooting for him and are keeping him, Jill, and the entire family in our thoughts.”
