The final night of the 2020 Democratic National Convention features tributes to Beau Biden, the presidential nominee's son who died following a brain cancer diagnosis in 2015.

Joseph "Beau" Biden III, an Iraq War veteran and Delaware attorney general, was 46.

"He's the one who wanted me to stay engaged," Joe Biden said in a video that introduced Thursday's prime-time event. "He was worried that I would not continue to fight for the things I'm passionate about, and I'm trying to keep that promise."

Under Barack Obama's administration, then-vice president Biden launched a "Cancer Moonshot" program aimed at ending cancer.

Beau Biden had experience a stroke in 2010 and was treated three years later at MD Anderson Cancer Centre in Houston, Texas, where doctors removed a lesion from his brain.

But his cancer returned, and he received aggressive treatment at Walter Reed National Military Medical Centre in Bethesda, Maryland.

He was survived by his wife Hallie and his two children Natalie and Hunter.

Beau Biden was 2 years old when his mother Neilia was killed in the crash that also took the life of his sister Naomi. Beau and his brother Hunter, then 3 years old, were also in the car. Their father was set to be sworn into his first term as a junior US senator from Delaware.

During his 2012 speech at the convention, in a speech introducing his father's renomination to vice presidency, Beau Biden was moved to tears.

"One of my earliest memories was being in that hospital, Dad always at our side," he said. "He decided not to take the oath of office. He said, 'Delaware can get another senator, but my boys can't get another father.' However, great men like Ted Kennedy, Mike Mansfield, Hubert Humphrey – men who had been tested themselves – convinced him to serve. So he was sworn in, in the hospital, at my bedside."

Biden famously made a daily commute to Washington DC by train, earning him the nickname Amtrak Joe, as he raised his two young boys.
