A group of Bernie Sanders supporters and other protesters disrupted an appearance by Hillary Clinton in southern California.

The Democratic presidential frontrunner was repeatedly interrupted Thursday as she spoke to a largely Latino crowd in Monterey Park, where Union del Barrio organized a protest against Clinton over her immigration policies and opposition to a national $15 hourly minimum wage, reported KNBC-TV.

Clinton warned that Donald Trump, the presumptive Republican presidential nominee, would create a “deportation force to round up millions of people” — but her opponents remained unconvinced by her message.

“She would do absolutely nothing to help the middle class,” said Cilena Aziz, a Sanders supporter.

Protesters chanting, “she’s not with us,” forced Clinton to cut short her scheduled speech to just 14 minutes — and signaled she may have a difficult time rallying Sanders supporters behind her campaign if she wins the Democratic nomination.

“I believe that being a Democrat is for the people,” said Regina Cruz, a Sanders supporter. “I have a really difficult time believing that she is really for the people.”

Clinton also met with a group of politically influential black pastors at the California African American Museum in Exposition Park and then attended a fundraiser hosted by Jose Huizar, a Los Angeles city councilman.

She has said a strong showing in California’s June 7 primary could put her on the path to winning November’s general election and push her opponent out of the Democratic primary race.

“I am 3 million-plus votes ahead of Senator Sanders, right?” Clinton said in Exposition Park. “I am nearly 300 pledged delegates ahead of Senator Sanders.”
