Former Vice President Joe Biden has worn rosary beads every day since his son Beau died in 2015.

Biden appeared on Megyn Kelly Today on Monday to discuss his new book, Promise Me, Dad, which recounts Beaus brain cancer diagnosis and eventual death.

Sitting beside wife Dr. Jill Biden, the former vice president opened up about the necklace he wears around his wrist, which he said connects him to his late son.

I have not taken off the rosary Beau was wearing when he passed, since then. It is my connection with him, Biden said.
