Story highlights Vermont Sen. Bernie Sanders said Monday that he expects the Democratic convention to get "messy" this summer

Sanders and his campaign manager said the comment did not refer to or condone violence at the convention

Washington (CNN) Bernie Sanders stood by his suggestion that the Democratic convention will get "messy," but his campaign manager said Tuesday the Vermont senator didn't mean violence and that the word describes the conversations essential to doing the "business of the party."

"If we can't get the platform planks that the Senator supports in the platform during the committee process, if we can't get the electoral reform that the Senator is advocating, then of course those things would have to go to the floor for voters during the convention," Jeff Weaver said Tuesday on CNN's "New Day."

Weaver told CNN's Alisyn Camerota there's no concern that Sanders supporters will misinterpret "get messy" as advocating aggression; they know that it means heated debate.

"We're just going to have votes on the floor of the convention. That's all. There will be debate and there will be votes," he said. "You don't often see that anymore in modern conventions. But in fact, that's what conventions are really about -- for parties to do the business of the party."
