Larry Sanders said he hopes supporters of his brother Bernie will heed the Vermont senator's advice and vote against GOP presidential nominee Donald Trump in November.

“But I will understand very fully if they decide otherwise because the Hillary (Clinton) camp has been very stupid,” said Sanders, who was in Philadelphia on Monday for the Democratic National Convention.

The elder Sanders, who lives in Oxford, England, and has served on his county council, said leaked emails that reveal efforts by the Democratic National Committee to undermine his brother's presidential campaign are a “disgrace.”

And he said it’s “not very nice” that presumptive Democratic nominee Hillary Clinton appointed Rep. Debbie Wasserman Schultz of Florida — who said Sunday she'll step down as head of the DNC amid the controversy — to be "honorary chair” of Clinton’s 50-state program to elect Democrats.

“It seems to me a kick in the teeth,” he said

Sanders said the protests by his brother’s supporters have been “very affecting” because of the “enormous amount of love” they’ve shown for his brother.

“I’ve never seen that connected with a politician before,” he said.

Larry Sanders said he has no advice for his younger brother as Bernie Sanders prepares to deliver opening remarks at the Democratic convention Monday night.

“I stopped doing that 40 years ago,” he said. “He’s a much better politician than me.”

He said his brother will tell the convention why he ran and what he thinks the Democratic Party will become.

“The Democratic Party will have to decide whether it wants to be the party of the future or the party of big business,” he said. “It has a choice.”
