Rosario Dawson says she's "grateful" following her arrest in Washington, D.C. on Friday.

The Daredevil actress was arrested for crowding, obstructing or incommoding after crossing police lines during the Democracy Spring rally at the U.S. Capitol, ET has confirmed. While she was not handcuffed, Dawson was given a ticket for a $50 fine and was processed on site.

"This is a tremendous issue and I'm really grateful that I could be here and be a part of it," the 36-year-old actress told reporters following her arrest. "I wanted for me, personally, to be in solidarity with the people who put themselves on the line."

Dawson, who wore a leather jacket painted with presidential candidate Bernie Sanders' face on it, attended the nonviolent protest to "end the corruption of big money in our politics," Democracy Spring explains on their website.

"These are really important issues and the people really need them, and we're putting ourselves on the line for what a lot of people across America and across the planet really want to be able to see happen in America," Dawson explained. "Which is one person, one vote and to take the money out of politics, so we can have fair elections with real progressives."

Dawson said she was warned multiple times that she would be arrested and suggested that the cops may not have wanted to arrest her because they knew she was a celebrity and would draw attention. Still, in the end, she said, "The police were really great with us and really lovely, I have to say that is not the case for so many people."
