Vice President Joe Biden on Wednesday said that if a another situation like the chaos at the Nevada Democratic Convention occurs again, Sen. Bernie Sanders (I-VT) will need to be more vocal in condemning the actions of his supporters.

“That’s not Bernie,” Biden told reporters in Ohio when asked about the ruckus from Sanders backers at the Nevada convention over the weekend, according to the Huffington Post. “And what Bernie’s going to have to do if that happens again — he’s going to have to be more aggressive in speaking out about it.”

“Bernie Sanders is a good guy. Let Bernie run the race. There’s nothing wrong with that,” the Vice President added.

Biden also said that he’s not concerned about Democratic party unity.

“I’m confident that Bernie will be supportive if Hillary wins, which the numbers indicate will happen,” he said. “So I’m not worried. There’s no fundamental split in the Democratic Party.”
