'That's My Dad': Gus Walz Steals On Show At DNC: Photos

CHICAGO — The third night of the Democratic National Convention was a star-studded event, featuring Oprah Winfrey, Stevie Wonder, and former President Bill Clinton. And Vice President Kamala Harris' running, Minnesota Gov. Tim Walz, introduced himself to the nation.

But it was the governor's 17-year-old son, Gus, who stole the show.

As Tim Walz delivered his speech on stage at the packed United Center, he gave an emotional shoutout to his family in the crowd: "Hope, Gus and Gwen. You are my entire world and I love you," Walz said.

A teary-eyed Hope, 23, made a "heart" gesture with her hands toward her dad. Gus, crying and overwhelmed with emotion, began clapping stoop up and tearfully pointed to his father and cheered: "That's my dad!"

The moment quickly went viral across social media platforms, with commenters saying they enjoyed seeing Gus's raw, authentic outpouring of love for his father.

Hope and Gus were born after the couple’s long struggle with infertility.

In an August interview with People magazine, the Walz family shared that Gus has a non-verbal learning disorder, as well as ADHD and anxiety.

"When our youngest Gus was growing up, it became increasingly clear that he was different from his classmates," Tim and Gwen told the magazine in a statement. "Gus preferred video games and spending more time by himself."

"When he was becoming a teenager, we learned that Gus has a non-verbal learning disorder in addition to an anxiety disorder and ADHD, conditions that millions of Americans also have."

The couple went on to say that "it took time, but what became so immediately clear to us was that Gus’ condition is not a setback — it’s his secret power."
