Former Vice President Joe Biden set political differences aside on "The View" when he consoled Meghan McCain over the cancer diagnosis of her father, Republican Sen. John McCain of Arizona, telling her that there's "hope."

Sen. McCain was recently diagnosed with the glioblastoma, the same cancer that took the life of Biden's son, Beau, in 2015.

The former vice president also talked about how there are cancer therapy breakthroughs every day, but he kept coming back to Sen. McCain's courage.

"The View" co-host brought up her father's illness while talking with the former vice president on the show Wednesday, saying that she thinks about Beau "almost every day," but she wasn't able to talk about it very long before breaking down.

Biden quickly consoled Meghan, telling her “there’s a lot of hope.” He then went on to talk about how Beau and Sen. McCain had become friends years ago and told her how his son talked about her father’s courage.
