From a classroom at Brandywine High School, where she once taught English, Jill Biden said her husband Joe Biden could heal a struggling nation.
"The burdens we carry are heavy, and we need someone with strong shoulders," she said. "I know that if we entrust this nation to Joe, he will do for your family what he did for ours -- bring us together and make us whole. Carry us forward in our time of need. Keep the promise of America for all of us."
In a speech that focused on families, including Biden's own, Jill Biden made a personal case for her husband's character. She touted his resolve after his son Beau Biden died in 2015, and said it's what the nation needs amid the personal fallout of the coronavirus pandemic.
"We're coming together and holding onto each other. We're finding mercy and grace in the moments we might have once taken for granted. We're seeing that our differences are precious and our similarities infinite," she said. "We have shown that the heart of this nation still beats with kindness and courage. That's the soul of America Joe Biden is fighting for now."
Her speech also addressed, in the most specific way in the first two nights of the DNC, how the pandemic has shuttered many schools, left children learning virtually and forced parents to adapt.
"I hear it from so many of you, the frustration of parents juggling work while they support their children's learning, or afraid their kids will get sick from school," she said.
"These classrooms will ring out with laughter and possibility once again," she said.
