The Nevada convention erupted in bedlam on Saturday, with supporters of Sanders's presidential campaign loudly protesting the delegate selection process and booing Boxer, who supports Hillary ClintonHillary Diane Rodham ClintonThe 'Palmetto Promise': South Carolina will decide the race Alabama Senate contender hits Sessions in new ad: 'Hillary still ain't in jail' Worries grow as moderates split Democratic vote MORE.

Boxer said that she tried to defuse the situation during her convention address.

“I basically told the crowd, ‘Bernie and Hillary had asked for civility,’ ” Boxer said. "That didn’t help. I said, ‘Bernie’s a friend, he’s my good friend.' They still booed.”

Boxer said she spoke to Sanders on Tuesday evening.

“He was very distressed about it,” she said. "He expressed shock that his people would do it. It was a very warm conversation.

“I expect Bernie to get a hold of this whole situation. That’s what I expect from a leader. Bernie has shown that he is a leader in this country. We need to unite.”

The Nevada Democratic Party on Monday warned that Sanders supporters could stir up “actual violence” at the Democratic National Convention in July.

Sanders on Tuesday called those accusations “nonsense,” and maintained that the state party had treated his campaign unfairly in Nevada.

“The Democratic leadership used its power to prevent a fair and transparent process from taking place,” he said in a statement.
