Civil rights activist Dolores Huerta, who has endorsed Clinton, told CNN that the comments came when she offered to translate herself.
"Then some of the organizers were shouting 'English only, English only.' This is bad."
Actress America Ferrera, who is also backing Clinton, took to Twitter to also share her observations from the Harrah's casino site.
Harrah's casino site- Bernie supporters chant "English-only" to stop civil rights leader @DoloresHuerta from providing Spanish translation.— America Ferrera (@AmericaFerrera) February 20, 2016
A video was posted online purportedly showing the moment, but the “English only” chant is not audible in the clip. Buzzfeed reported it has two neutral sources backing up Huerta's account.
But Sanders supporters, including actress Susan Sarandon, have pushed back on Huerta's claim.
Sarandon, who says she was also at the caucus site, tweeted out a link to video from the caucus and argued that a moderator said that the caucus would continue only in English once a translator could not be found.
Symone Sanders, Sanders's spokeswoman, told CNN that the campaign doesn't "condone" disrespectful actions by supporters.
"As the senator has said, this campaign is about bringing people together, not dividing them," she told the network.
"We expect our supporters to be respectful of all people and don't condone anything otherwise."
Clinton won the caucuses in large part from support from Clark County — the home of Las Vegas — sweeping major caucus sites held on the Las Vegas strip.
Her campaign highlighted Sanders's vote against immigration reform in 2007 as she sought to shore up her lead among Hispanic voters.
