House Minority Leader Nancy Pelosi released a statement Tuesday night condemning violence by members of the anti-facist movement Antifa during protests in Berkeley this weekend.

“Our democracy has no room for inciting violence or endangering the public, no matter the ideology of those who commit such acts,” Pelosi, who represents San Francisco, said in the statement. “The violent actions of people calling themselves antifa in Berkeley this weekend deserve unequivocal condemnation, and the perpetrators should be arrested and prosecuted.”

More than 100 members of Antifa — a loosely organized group that often shows up at right-wing protests — caused a ruckus at Berkeley’s Civic Center Park on Sunday. Most of the roughly 4,000 people who arrived to counter-protest a small group of Trump supporters were totally peaceful. But some of the hooded, masked and black-clad Antifa members started fights and punched or kicked people they believed were Trump supporters.

By day’s end, 13 people were arrested and two people were taken to the hospital.

“In California, as across all of our great nation, we have deep reverence for the Constitutional right to peaceful dissent and free speech,” Pelosi said. “Non-violence is fundamental to that right. Let us use this sad event to reaffirm that we must never fight hate with hate, and to remember the values of peace, openness and justice that represent the best of America.”

Right-wing organizers had called on Pelosi and other San Francisco leaders to condemn Antifa, accusing the politicians of tacitly allowing the group’s violence to go unchecked. Some conservative figures complimented Pelosi for the statement.

Others on the left, however, criticized Pelosi for her statement. Stephen Jaffe, who’s running a long-shot primary challenge against the 30-year incumbent, said she should focus on impeaching President Donald Trump, not attacking Antifa.
