Trump's youngest daughter Tiffany and eldest son Don Jr. addressed the crowd.

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."

Tiffany, the only child from the celebrity businessman’s six-year marriage to Maples, has achieved newfound celebrity status in the wake of her father's run for the presidency.

Tiffany’s oldest stepbrother Donald Trump Jr. also addressed the arena, and praising his father as his “mentor.”
