For the second time in a month, Bernie Sanders has been derailed by Black Lives Matter activists. The last time was at the Netroots Nation conference in Phoenix. This time it was at a campaign rally in Seattle, WA.

John Wagner of the Washington Post reports:

Bernie Sanders leaves Seattle stage after event disrupted by Black Lives Matter protesters

A planned speech in Seattle by presidential hopeful Bernie Sanders celebrating the anniversary of Social Security and Medicare was scuttled Saturday after protesters from Black Lives Matter took the stage and demanded that the crowd hold Sanders “accountable” for not doing enough, in their view, to address police brutality and other issues on the group’s agenda…

Shortly after the senator from Vermont started speaking, a small group of protesters took the microphone, shared a series of local grievances with the crowd, including school disparities and gentrification in Seattle, and then asked for a period of silence to commemorate the one-year anniversary of Michael Brown being shot and killed during a confrontation with a police officer in Ferguson, Mo.

Here’s a video of the activists taking over the podium while shouting that they would not be silenced:
