Joe Biden jokes that Donald Trump is "too old and mentally unfit to be president" The 81-year-old Democratic candidate made the joke at a dinner in Washington, D.C. Joe Biden spoke at the Gridiron Club and Foundation dinner, a Washington tradition.
It was his first time attending as president. He also responded to the ambiguous remarks made by Donald Trump during the day, evoking a “butchery” for the economy of the U.S. United if he was not elected.
