Story highlights Donald Trump's youngest daughter made campaign debut

Tiffany Trump is the only child of Trump and Marla Maples

(CNN) Donald Trump's youngest daughter, Tiffany, defended her father's treatment of women during her campaign debut Tuesday night at CNN's family town hall event in New York City.

The 22-year-old is a senior at the University of Pennsylvania and registered -- unlike two of her more prominent half-siblings -- to vote in that state's upcoming Republican primary.

The only child of Trump and his second wife, Marla Maples, Tiffany has in the past few months made her first appearance as a runway model and emerged as a minor celebrity on Instagram. She was, according to Town and Country Magazine , named after the "Tiffany's," the luxury New York City jewelry store.

But rather than embracing the tabloid life or hitting the stump with her father, she has focused more on school and a minor social media campaign to boost her mother's turn on this season of "Dancing With The Stars." (Maples was eliminated on Monday night.)

Not that she isn't a fan of her father.
