A Hispanic worker at Trump Hotel in Las Vegas says Republican presidential nominee Donald Trump treats his cleaning staff like “second-class workers” in a Spanish-language radio ad from Hillary Clinton’s campaign.

The ad released Monday is set to air in Nevada and Ohio, two important battleground states.

{mosads}A voice over introduces Carmen, the Trump Hotel worker, describing the luxury finishings of the hotel.

“But those who work for Donald Trump will tell you, everything that glitters isn’t gold,” says the voiceover.

“He treats us like we’re second-class workers. He has no respect for us. We’re the people who come here every day to clean his building, prepare the rooms, so he can be successful,” says Carmen.

The ad ends with an appeal for eligible voters to register and vote.

Clinton, the Democratic presidential nominee, has aggressively courted Hispanic voters, hoping that Trump’s low approval ratings among the demographic could bring her wins in states such as Nevada with high Hispanic populations.

The worry for Democrats is that Hispanics traditionally have low turnout numbers.

Democrats have targeted battleground states with large Hispanic populations for months — mainly Colorado, Florida and Nevada — and have recently pushed into smaller Hispanic communities in tight swing state races like Iowa and Ohio.

The most recent RealClearPolitics average of Ohio polls shows a 1.8-point Trump lead, and Hispanics make up 3.3 percent of the state’s population.
