Joe Biden Just Made The Most Touching Tribute To His Son!

Perhaps the only time Joe Biden ever had a real chance of running for the White House, his oldest son, Beau, was dying from brain cancer.

The former vice president is now chronicling 2015, as one of the hardest years of his life, in his new book, “Promise Me, Dad: A Year of Hope, Hardship and Purpose.”

In a new clip from the audio recording of his book, Biden describes how his son served as a reminder to stay true to his roots.

“Beau would always grab my arm just before I walked on stage and pull me back toward him until I was looking into his eyes,” Biden says in the clip. “’Dad, look at me. Look at me, Dad. Remember, Dad. Home base, Dad. Home base.’ What he was saying was, remember who you are. Remember what matters. Stay true to your ideals. Be courageous.”

“A listening experience made visceral and intimate by Biden’s own voice, ‘Promise Me, Dad’ chronicles the twelve months when the vice president balanced the twin imperatives of living up to his responsibilities to his country and focusing on his family while his son Beau battled brain cancer,” according to an Audible press release. “Never far away was the insistent question of whether he should seek the presidency in 2016.”
