Brain cancer took the life of 46 year old Beau Biden.
The Vice President’s son was taken to Walter Reed National Military Medical Center last month but at the time there was no word on why he was being treated.
The former Delaware Attorney General and rising political star in the Democratic Party had been diagnosed with brain cancer two years ago.
He also suffered a mild stroke in 2010.
Biden decided against a third term as Attorney General setting his sights on the governorship next year.
Reactions poured in at the news of his death.
