WATCH: Presidential candidate breaks down in tears talking about gun crime

Andrew Yang was overwhelmed by a mother's story of her child's death.

Presidential candidate Andrew Yang was reduced to tears while discussing gun crime at a town hall meeting in Iowa on Saturday.

Yang, who is a Democratic candidate, was told a story by a mother who explained how her 4-year-old daughter was killed by a stray bullet as her other son looked on.

Yang tried to respond to the woman, but got visibly choked up, before stopping completely altogether.

He got back on track and managed to speak about his thoughts on gun crime, saying: "I have a 6 and 3-year-old boy and I was imagining it was one of them that got shot and the other saw it -- that scene that she described, I'm sorry. It's very, very affecting."

He also discussed the dangers of having a gun in your household, and how you are more likely to do damage to yourself or your family rather than a potential intruder.

Yang has been endorsed by a number of high profile names, including Elon Musk, and is campaigning as "the opposite of Donald Trump."

He is currently polling at around 2%.
