Joe Biden comforts John McCain's daughter in emotional moment on 'The View'

Joe Biden and Meghan McCain

NEW YORK CITY — There was a touching moment on "The View" Wednesday morning while former Vice President Joe Biden was a guest.

Biden was promoting his new book, "Promise Me, Dad," which is about his son's terminal cancer battle.

Meghan McCain, who is a co-host, introduced Biden by explaining that her father, Sen. John McCain was recently diagnosed with the same type of cancer that took Biden's son's life. She teared up and became emotional when talking about Biden's book, which then prompted Biden to move seats closer to her and hold her hand as they spoke about the cancer.
