WATCH: Bernie Sanders' Brother Casts Vote at Convention in Highly Emotional Moment

Larry Sanders addressed convention during roll call , speaking as a member of the Americans Abroad delegation. Sanders appeared to be near tears when he said their late parents would have been proud of the Vermont senator's accomplishments.

It’s a tearful night for some Bernie Sanders supporters at this year’s Democratic National Convention, as delegates from all 57 U.S. states and territories cast their votes, handing Secretary Hillary Clinton the Democratic presidential nomination.

But one tearful moment stood out among the rest for Sanders enthusiasts.

Larry Sanders, Bernie’s brother, cast his vote at Wells Fargo Arena as a delegate for Democrats Abroad (Larry lives in Great Britain). Offering a heartfelt tribute to his parents and his brother’s political campaign, Larry became emotional as he cast his vote.

“They did not have easy lives,” Larry Sanders said of their parents. “And they died young, but they would be immensely proud of their son and his accomplishments.”
