Ben Cohen and Jerry Greenfield, the co-founders of Ben & Jerry's ice cream, were arrested on Monday in a massive leftist protest at the US Capitol, reports CNN on Tuesday.
The two, together with around 300 other people, were taking part in "Democracy Awakening" protests held in Washington DC over the weekend.
"Democracy Awakening" is meant to "protect voting rights, get big money out of politics and demand a fair hearing and an up or down vote on President Obama's Supreme Court nominee," according to its website.
Other hot topics targeted in the protests are climate change, racial justice, workers' rights, safe food and water, health care, peace, immigration reform, and education.
US Capitol Police said in a statement that the protesters were arrested for holding an unlawful demonstration, and were processed on the site before being released.
While "Democracy Spring" appears highly leftist, it is not directly affiliated with any party or candidate. Both Greenfield and Cohen have been highly outspoken on politics, vocally supporting the openly socialist Democratic candidate Bernie Sanders.
Sanders is an Independent Senator from Vermont where Ben & Jerry's is based, and Cohen personally endorsed him and took part in the launch of his presidential campaign.
Recently Ben & Jerry's has put out a new ice cream flavor especially for Sanders, called "Bernie's Yearning."
Cohen told CNN last October that the ice cream flavor is to be mint flavored topped with a huge chocolate chip that "represents all the wealth that's gone to the top 1% of the population over the past 10 years."
"And the way you eat it is that you whack it with your spoon, then you mix it around. That's the 'Bernie's Yearning,'" Cohen said, giving Sanders' socialist "yearning" a culinary expression.
On Tuesday Cohen and Greenfield planned to campaign for Sanders in Delaware, where they were to hand out free ice cream.
In recent weeks Sanders has been leading an ever more openly anti-Israel campaign, which recently including intimations that he would be even more on the Palestinians' side than US President Barack Obama.
