Before Joe Biden officially accepted the Democratic nomination for president, his family had something to say. The former vice president was honored with a video featuring his adoring granddaughters, who revealed that they speak to him everyday — and begged him to run for president. Speeches then came from his two children: daughter Ashley Biden, 39, and son Hunter Biden, 50. But before honoring their father, they honored someone dear to them: their brother, Beau Biden.
