Former Vice President Joe Biden accepted the Democratic presidential nomination and delivered a speech at the DNC on Thursday night.
Biden laid out his vision for the nation. He promised to end what he called a "season of darkness."
Biden said: "Our current president is failed in his most basic duty to the nation. He's failed to protect us. He's failed to protect America, and my fellow Americans, that is unforgivable," Biden said. "As president, I'll make you a promise: I'll protect Americans. I will defend us from every attack -- seen and unseen -- always, without exception, every time."
