Tiffany, dressed in blue, spoke self-deprecatingly of her newness to the national stage, and praised her father's capacity to inspire people and lead.
"He's always helped me be the best version of myself," she said of her father.
She added that the qualities that made him a great father would also make him a great president.
"He brings out the challenge and drive in people," she said, calling him a "natural born encourager."

She grew up in California with her mother and the two are reportedly very close. She graduated in May from the University of Pennsylvania as part of the same class as Joe Biden's granddaughter, Naomi Biden.
"I never pictured myself saying this to a packed arena," she added of the experience of endorsing her father for president.
