Actress and pro-Bernie Sanders activist Rosario Dawson has been arrested on Friday night, pop culture website TMZ reports.
Dawson was among about a dozen people arrested at the Democracy Spring rally going on in Washington, D.C.
The rallies are protesting against big money and corruption in politics, and the demonstrators have marched on the Capitol Building to stage sit-ins and other forms of non-violent protest. It began earlier this week.
As of now, there is no further information on her arrest.
The news comes the day after Sanders and former Secretary of State Hillary Clinton debated in Brooklyn. During the debate, Clinton was pressed to release transcripts of her speeches to Wall Street firms. She retorted that Sanders should release his tax returns, as she has done.
Sanders has released his tax returns for 2014, in which he reported an income of slightly more than $200,000.
Meanwhile, Clinton's speaking fee for Wall Street is in the neighborhood of $225,000-$325,000, meaning she often made more money in a matter of hours than Sanders does in a year.
A CNN analysis found that Hillary Clinton and her husband, former President Bill Clinton, earned a combined $153 million in paid speeches between February 2001 and last May.
