Tim Walz’s visibly emotional son leapt to his feet as his father gave a speech at the Democratic National Convention.
Mr Walz, who formally accepted the Democratic party’s nomination for vice-president on Wednesday, was met with cries of “that’s my dad” from his 17-year-old son Gus as he delivered the address.
“Hope, Gus and Gwen, you are my entire world and I love you,” Walz said during the speech in Chicago.
Gus hugged his father on stage after the speech ended.
Mr Walz’s wife described Gus as “brilliant” in an interview with People magazine, in which she revealed he had a learning disorder, ADHD and an anxiety disorder.
