The Nevada State Democratic Party on Monday said Sanders’s backers may instigate “actual violence” at the Democratic National Convention in Philadelphia this summer.

Sanders on Tuesday called such accusations “nonsense,” adding that the Nevada Democratic Party had unfairly impeded his presidential campaign.

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

“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.” 

Feinstein on Wednesday said that Sanders’s remarks were too lenient after the severity of last weekend’s events.

“That was the time to send a full-throated message to his followers that we don’t do this kind of things,” said Feinstein, who has previously endorsed Democratic presidential front-runner Hillary ClintonHillary Diane Rodham ClintonO’Rourke heading to Wisconsin amid 2020 speculation The Hill's 12:30 Report — Presented by Kidney Care Partners — Lawmakers scramble as shutdown deadline nears Exclusive: Biden almost certain to enter 2020 race MORE.
