One of the most touching moments of the third night of the Democratic National Convention was when Tim Walz‘s son Gus broke down in tears as he watched his dad take the stage.

The Minnesota Governor appeared at the DNC on Wednesday night (August 21) to accept the Democratic nomination for Vice President of the United States.

Tim‘s wife Gwen and kids Hope and Gus were in the audience cheering him on as he took the stage. 17-year-old Gus went viral for his heartwarming reaction!

During his speech, Tim told his family, “Hope, Gus and Gwen – you are my entire world, and I love you.”

Gus adorably got out of his chair, pointed at his dad, and said, “I love you, dad.”

For those who don’t know, Gus has ADHD, as well as an anxiety disorder and a non-verbal learning disorder. His parents previously said, “Like so many American families, it took us time to figure out how to make sure we did everything we could to make sure Gus would be set up for success as he was growing up. It took time, but what became so immediately clear to us was that Gus’ condition is not a setback — it’s his secret power.”
