Chelsea Clinton on Thursday night portrayed Democratic presidential nominee Hillary Clinton as a devoted mother and grandmother and tireless advocate for children and women, relaying first-hand accounts of the candidate as a “fighter who never, ever gives up.”

The only child of Hillary and Bill Clinton introduced her mother for her history-making nomination acceptance speech capping at the Democratic National Convention in Philadelphia.

“I never once doubted that my parents cared about my thoughts and my ideas,” Clinton said. “That feeling of being valued and loved, that’s what my mom wants for every child. It is the calling of her life.”

Chelsea Clinton, 36, who spent her formative years growing up in the White House while her father served as president, is now a Manhattan philanthropist and mother of two young children.

Ivanka Trump last Thursday night at the Republican National Convention in Cleveland similarly served as a character witness to her father, Donald Trump, the GOP nomminee for president.

Donald Trump in a Fox News interview said earlier Thursday he was looking forward to Chelsea Clinton’s speech, noting that his daughter Ivanka “has a lot of respect” for her contemporary.

Unlike Ivanka Trump, Chelsea has shied from the spotlight despite the celebrity of her parents.

She appeared nervous onstage but spoke for roughly 12 minutes, in part about how her mother always made time to read to her and to attend her soccer and softball games and piano and dance recitals despite her busy schedule as first lady.

The younger Clinton said she grew up witnessing her mother’s dedication to health care and education, recalling Hillary Clinton’s “bruising” loss in 1994 in her quest for universal health care.

“It was bruising, it was exhausting. She fought her heart out, and as all of you know, she lost,” Chelsea Clinton said.

But she added that her mother always carries on amid the “fury of politics,” because “she never, ever forgets who she’s fighting for.”

“Public service is about service, and as her daughter, I got a special window into how she serves,” Chelsea Clinton said. “She always feels like there isn’t a moment to lose, because she knows that for that mother, for that family, there isn’t.”
