After Trump supporters said they would hold a "Patriot Day" rally, counter-protesters made a decision to hold a rally at the same place. Police initially reported 15 arrests, but later tweeted out a correction.
Though barricades were erected to separate the rival groups gathered at the Civic Center Park, the rallies quickly spilled out into the streets. Right-wing groups held Trump campaign signs and posters that read "Free speech", among others. "That's a message I can get behind". Wyden, the ranking Democrat on the Senate finance committee, has introduced legislation that would require sitting presidents, including Trump, to release their tax returns for the past three years.
City officials said, "Mass gatherings of any kind attract a broad variety of people and, inevitably, that means an array of different motives and intentions".
Among the Trump opponents were some counter-protesters dressed in black and wearing masks. Trump's break with precedent has raised questions about possible conflicts of interest.
One person at the riot was Nathan Damigo, a white nationalist and student from California State University, Stanislaus in Turlock, who was caught on video punching a woman according to The Sacramento Bee.
With backing of dozens of organizations, Tax Marches are happening in New York City, Washington D.C., Chicago, Seattle, West Palm Beach and more than 100 others.
