Biden told reporters he did not have details of the event and has not yet called King Charles.
"(Journalist asking : Are you going to the Queen’s funeral, Sir.?) Yes. I don’t know what the details are yet but I will be going. (Journalist asking: Have you called the King? Have you spoken to the King?) I know him, I haven’t spoken with him. I did not call him yet.”
Britain has declared a period of mourning until the state funeral, which will be held in a little over a week's time.
Dignitaries from around the world are expected.
