As Joe Biden formally became the Democratic presidential nominee, a 13-year-old boy from New Hampshire emerged as the virtual convention's highlight.
Brayden Harrington delivered a speech urging people to vote for Mr Biden.
On the face of it, not particularly remarkable, but Brayden captured the imagination of many as he conveyed his message while having a stutter.
He revealed how he had been inspired by Mr Biden because the nominee, too, had a stutter.
In a video that has been viewed more than two million times, Brayden started his speech by saying: "Without Joe Biden, I will not be talking to you today."
The pair met in New Hampshire a few months earlier when Mr Biden told Brayden that they were "members of the same club - we stutter".
Brayden said he was amazed to see that someone similar to himself had become the vice-president of the United States.
He went on to say how Mr Biden had made him feel "confident" about his stutter, which he has lived with his whole life.
He closed his speech with a plea to US voters: "Kids like me are counting on you to elect someone we can all look up to, someone who cares, someone who will make our country and the world feel better."
Why do some children stutter?
- The most common form of stuttering starts in some children between the ages of 2-5
- It occurs when speech and language skills are developing quickly
- Doctors are not completely sure what causes it but it is not thought to be anything their parents have done
- It affects boys more often than girls
Veteran journalist and broadcaster, Dan Rather, described Brayden as "pure, unvarnished, courage".
Former Arizona congresswoman, Gabrielle Giffords who was shot in the head while in office in 2011, tweeted how she could relate to Brayden.
"Speaking is hard for me too, Brayden," she says. "But as you know, practice and purpose help. Thank you for your courage and for the great speech."
In a Twitter thread, journalist Elie Mystal said her mother, who is a speech pathologist, was "coaching" him through his speech.
I'm still floored by the Brayden thing. My mom is a speech pathologist. She was like *coaching* him through his amazing moment.— Elie Mystal (@ElieNYC) August 21, 2020
And, so, it just wasn't lost on me that Biden was, even in his greatest moment, also showing Brayden that everything in life is possible for him.
Journalist Philip Lewis called Brayden's address the "speech of the night".
And writer Meena Harris said that Mr Biden would be happy that Brayden "stole the show".
Brayden Harrington stole the show, and I think that would make Joe very happy. ❤️— Meena Harris (@meenaharris) August 21, 2020
Journalist and author Kurt Eichenwald echoed the sentiments of many when he tweeted: "I hope Brayden follows Twitter so he knows how proud of him the whole country is."
