Tonight, I’d like to honor someone who has dedicated his life to serve this country: Justice Stephen Breyer—an Army veteran, Constitutional scholar, and retiring Justice of the United States Supreme Court. Justice Breyer, thank you for your service. 
One of the most serious constitutional responsibilities a President has is nominating someone to serve on the United States Supreme Court. 
And I did that 4 days ago, when I nominated Circuit Court of Appeals Judge Ketanji Brown Jackson. One of our nation’s top legal minds, who will continue Justice Breyer’s legacy of excellence.
## Document 1
One was stationed at bases and breathing in toxic smoke from “burn pits” that incinerated wastes of war—medical and hazard material, jet fuel, and more. 
When they came home, many of the world’s fittest and best trained warriors were never the same. 
Headaches. Numbness. Dizziness. 
A cancer that would put them in a flag-draped coffin. 
I know. 
One of those soldiers was my son Major Beau Biden. 
We don’t know for sure if a burn pit was the cause of his brain cancer, or the diseases of so many of our troops. 
But I’m committed to finding out everything we can. 
Committed to military families like Danielle Robinson from Ohio. 
The widow of Sergeant First Class Heath Robinson.  
He was born a soldier. Army National Guard. Combat medic in Kosovo and Iraq. 
Stationed near Baghdad, just yards from burn pits the size of football fields. 
Heath’s widow Danielle is here with us tonight. They loved going to Ohio State football games. He loved building Legos with their daughter.
