The ongoing protests in Minneapolis over the fatal police shooting of Jamar Clark earned a public endorsement from a high-profile presidential candidate.

Bernie Sanders, who is running for the Democratic party's nomination,

" target="_blank">said on Twitter Friday morning "we stand with those who want the truth to be revealed," and included the #Justice4Jamar hashtag that's been an online symbol of the demonstration.

The tweet from Sanders, the senator from Vermont and a self-described democratic socialist, was a response to Minnesota U.S. Rep. Keith Ellison, who on Twitter linked to his own statement on the Jamar Clark protests.

The Congressman urged the Bureau of Criminal Apprehension to release surveillance video of the shooting – which is a demand of the protesters – but the agency says that won't happen until the investigation is complete.

Ellison was outside a decidedly less tense Fourth Precinct Thursday night, and was joined by other elected officials Minneapolis Mayor Betsy Hodges, and City Council members Lisa Bender, Alondra Cano and Cam Gordon.

The Democratic representative for Minnesota's Fifth Congressional District also shared his concerns when a Star Tribune photo of his son, standing in front of a police officer whose weapon was up, was widely circulated.

Ellison publicly threw his support behind Sanders last month, saying the 74-year-old has "demonstrated a willingness to push for progressive ideas that will help American families and restore balance to our economy."

In September, Sanders met with Black Lives Matter members after criticisms he was out of touch with the black community, the Huffington Post reported. Then at a debate in October, Sanders – when asked directly about it – said that "black lives matter." Sanders said there's a need to address "institutional racism," adding he'll look to reform the "broken criminal justice system."
