WATCH: Harris holds campaign rally and concert with Los Tigres Norte in Arizona

Vice President Kamala Harris held a campaign rally and concert with the Mexican norteño band Los Tigres Norte in Arizona on Thursday.

Watch the event in the player above.

Arizona is one of four states in the nation’s Sun Belt that has drawn much of the focus of both presidential campaigns in the final sprint to Election Day.

Harris has a new campaign ad in Spanish that will air in battleground states that seizes on comments made about Puerto Ricans during a Donald Trump rally in New York.

The ad, in Spanish, questions why Tony Hinchcliffe, a comic at Trump’s rally at Madison Square Garden, would call the U.S. territory a “floating island of garbage.”

The ad’s announcer says: “This Nov. 5 Trump will understand that some people’s trash is others’ treasure.”

The ad is part of a larger $370 million buy, and will air on Univision and Telemundo during high viewership telenovelas, and on digital platforms including El Nuevo Día, YouTube and Snapchat.

Since the rally, Latino celebrities and leaders have come out in support of the Democratic nominee.

Puerto Rican reggaeton singer Nicky Jam withdrew his endorsement of Trump on Wednesday.

In a video statement posted to his Instagram, Jam says he thought Trump would be good for the economy. But after Hinchcliffe’s comments, he says can no longer support the former president.

Other Puerto Rican superstars have backed Harris, including Bad Bunny and Ricky Martin.
