“Party Leaders in Nevada, for example, claim that the Sanders campaign has a ‘penchant for violence.’ That is nonsense. Our campaign has held giant rallies all across this country, including in high-crime areas, and there have been zero reports of violence.”

He said he condemns violence and harassment, before adding that shots were fired into his campaign office in Nevada earlier this year.

Sanders said that at the Nevada Democratic convention on Saturday, “the Democratic leadership used its power to prevent a fair and transparent process from taking place."

“If the Democratic Party is to be successful in November, it is imperative that all state parties treat our campaign supporters with fairness and the respect that they have earned,” the Vermont senator added.

Sanders supporters were frustrated that Clinton, who won the state’s caucuses in February, was able to pick up additional delegates, despite the fact that they packed the convention.

The state party's chairwoman, Roberta Lange, reported death threats from backers of the Independent senator.

Earlier on Tuesday, Reid and Sanders spoke about the incident.

“He and I had a very long conversation,” Reid told reporters. “I laid out to him what happened in Las Vegas. I wanted to make sure he understands what went on there. The violence and all the other bad things that has happened there.

“He said that he condemns that. I’m confident he does. I’m confident he’ll be saying something about it soon,” he added. “I’m hopeful and very confident that Sen. Sanders will do the right thing.”

Democratic National Committee Chairwoman Debbie Wasserman Schultz also asked Sanders on Tuesday to condemn the violence.

“We will be reaching out to the leadership of both of our campaigns to ask them to stand with the Democratic Party in denouncing and taking steps to prevent the type of behavior on display over the weekend in Las Vegas,” she said in a statement.

And the White House spoke out against the violence.

“The president on a number of occasions has spoken out against violence and has certainly said a political dispute like this can never be used to justify violence or a threat of violence,” White House press secretary Josh Earnest told reporters Tuesday.
