(CNN) – Rudy Giuliani’s campaign released a new ad in Florida Friday that uses footage and photographs of 9/11 and the ruins of the World Trade Center to emphasize his leadership as New York City mayor.

“When corruption ruled, he challenged it. When welfare failed, he changed it. When crime thrived, he fought it. When government broke, he fixed it,” says the announcer in “It Matters,” over images of criminals in handcuffs and the exteriors of porn shops.

“And when the world wavered, and history hesitated, he never did,” he continues, over images and footage of people running from the site of the Trade Center attacks, and the former New York mayor embracing rescue workers. “Rudy Giuliani. Leadership. When it matters most.”

The campaign said the ad is airing in West Palm Beach, an area that is home to a large population of transplanted New Yorkers. Florida voters head to the polls January 29.
