Bloomberg reports that Bernie Sanders told Barbara Boxer he was “distressed” about threats from his supporters against Nevada’s Democratic Party State Chair.

Bloomberg’s Sahil Kapur breaks news with this report:

Sanders has reached out to multiple Senate colleagues in an attempt to assuage them. Among them is Senator Barbara Boxer of California, whose keynote speech at the Nevada state Democratic convention last weekend was disrupted by rowdy Sanders supporters in a situation she described as frightening and out of control.

Bernie is not happy about what happened:

Boxer said she conveyed her concerns to Sanders in “a really nice talk” with him Tuesday. “I told him how bad it was in Nevada. He said he was distressed about it, and he expressed chagrin about it. I told him ‘Bernie, you need to get a hold of it,’ and he said he would.” “He said, ‘I can’t believe my people would do this,'” said Boxer, who is stepping down from the Senate in January. “He got the point.”

Here’s what I wrote two weeks ago about Democratic unity:

I’ve worked on two vigorously contested Democratic presidential campaigns and I’ve seen rancor and animosity morph into solidarity and unity. It will happen in 2016. Hillary will be the Democratic nominee. Bernie will support her. They will appear together on stage in a show of unity. President Obama will do the same. So will Elizabeth Warren. And Donald Trump will realize what he’s up against.

Let’s keep believing in that vision.
