Pelosi was attending an an event in San Jose with California Reps.
As others have also stated, the group of protesters rejected the idea that Pelosi, along with Senate Minority Chuck Schumer (D-NY), should capitulate or make a deal with President Donald Trump over the Deferred Action for Childhood Arrivals (DACA) program. Barbara Lee, D-Calif., and Jared Huffman, D-Calif., struggled to speak over chants of "all 11 million", a reference to the estimated total number of undocumented immigrants now in the country.
Democrats are not the resistance of Trump.
Trump and House Speaker Paul Ryan (R-Wis.) both disputed that any deal had been agreed to.
But on Monday, Pelosi came face-to-face with people who say they would be directly affected by any change in policy.More news: Hurricane Irma: prayers for Barbuda at Southwark Cathedral service
The undocumented immigrant activists at Pelosi's speech said that Democrats carried considerable blame for the infrastructure that would allow mass deportations.
When the protesters began shouting again, Pelosi herself raised her voice.
They accused Mrs. Pelosi and her fellow Democrats of giving into Mr. Trump's "deportation machine" and accused her of using Dreamers as a "bargaining chip".
The protesters also called for Immigration and Customs Enforcement to be shut down.
On the sidewalk outside the building, she told ABC7 News they are fighting for comprehensive reform but the first act will be to pass something along the lines of the DREAM Act. "We want that to be the basis of how we go forward", she said.
