California Democrats who whipped up opposition to the weekend’s free speech rallies had little to say after radical leftist protesters, led by the antifa movement, attacked police and Trump supporters on Sunday in Berkeley, injuring six.

House Minority Leader Nancy Pelosi, who last week denounced the Patriot Prayer gathering in San Francisco as a “white supremacist rally,” had no public comment on the leftist violence.

Joey Gibson, leader of Patriot Prayer, who was chased and struck by masked antifa protesters in Berkeley before police rescued him, called on Mrs. Pelosi and San Francisco Mayor Ed Lee to denounce the leftist violence.

At Sunday’s melee, about 100 black-masked protesters jumped police barricades and chased down and attacked a small number of Trump supporters, resulting in 13 arrests and injuries to six people, including a police officer.

Mr. Baker joined Democratic leaders in signing a resolution denouncing white supremacy after Charlottesville, saying that “white nationalism and neo-Nazism are continuing to grow as menaces to societal order.”
