Joe Biden is sending "hope" to the McCain family.
The former vice president was a guest on The View on Wednesday, where he consoled Meghan McCain about her father, Sen. John McCain, who was diagnosed with glioblastoma, an aggressive form of brain cancer, earlier this year.
Biden is all too familiar with this form of cancer, as it's the same diagnosis his late son, Beau, received.
"I think about Beau almost every day," McCain said, tearing up. "I was told that this doesn't get easier. But you cultivate the tools to work with this and live with this. I know you and your family have been through tragedy that I couldn't perceive of. What would you tell people ... it's not about me, it's about everyone... "
Biden then got up from his seat, walked over to McCain and comforted her by holding her hand.
"Your dad, you may remember when you were a little kid, your dad took care of my Beau," Biden reminded her. "Beau talked about your dad's courage, not about illness. And look, there's a lot of things happening. If any of you have somebody who's diagnosed with glioblastoma, which is about as bad as it gets, there's breakthroughs that are occurring now ... and it can happen tomorrow."
Biden continued on, explaining some of the latest breakthroughs and studies that are being conducted to help cure this specific disease.
"So, there is hope," he reassured McCain. "And if anybody can make it, your dad -- her dad is one of my best friends."
"We're like two brothers who were somehow raised by different fathers or something," he added. "I said I know, and I mean this sincerely. I know that if I picked up the phone tonight and called John McCain, and said, 'John, I'm at 2nd and Vine in Oshkosh and I need your help, come,' he'd get on a plane to come. I would for him, too."
Biden ended the conversation by urging McCain to continue having faith.
"The thing that I found was, and Beau insisted on, your dad's going to insist on, is you gotta maintain hope," he explained. "There's hope. You have to have hope."

When McCain made her debut as a co-host for The View in October, she also started to tear up while talking about her dad's cancer.
"When you hear cancer, a nuclear bomb goes off in your life," she explained. "No matter who you are. I didn't realize how intense and disruptive and scary and hopeless and chaotic you would feel all day long."
