The Democratic National Committee hoped to dig into Donald Trump’s failed attempt to build a tower in New Orleans as it ramps up for a campaign sure to take shots at his reputation as a real estate developer and businessman.

But a request for city documents related to the project came up empty.

A DNC researcher filed a public records request with the city last week seeking correspondence, complaints, investigations and other documents related to scrapped plans to build a 70-story Trump International Hotel and Tower on Poydras Street. Wednesday afternoon, the city responded that the records requested do not exist.

The request is apparently part of a broader effort by both the DNC and presumptive Democratic presidential nominee Hillary Clinton to attack public perceptions of Trump as a successful developer, potentially undermining his campaign narrative.

The practice of seeking potentially damaging information about opponents, and using it in attacks, is a standard part of election year politics.

Clinton spent Wednesday morning in Atlantic City, N.J., blasting Trump for the failure of his casino ventures there and their multiple bankruptcies, according to the Associated Press. Clinton’s campaign is expected to begin rolling out stories from contractors on Trump projects who were never paid and other “victims” of his business practices in coming weeks, according to the AP.

When asked about the public records request, DNC Southern Regional Communications Director Deshundra Jefferson said in an email, “Donald Trump has threatened to do to the economy what he’s done with his businesses, so we believe the American people have the right to see what happened in his various business ventures. Across the country, he has outsourced instead of making American products, shortchanged small businesses and laid off workers. America deserves better.”

Trump, who is expected to receive the Republican nomination, announced the 700-unit tower project, which would have been the tallest building in the New Orleans, just days before Hurricane Katrina struck in 2005. But rising labor and material costs after the storm forced the price tag for its proposed condos ever higher, with units projected to cost from $400,000 for a studio to a few million for a penthouse suite.

The project eventually floundered and the parking lot where it would have been built was sold at a foreclosure auction in 2011.

How directly Trump was involved in the project is unclear; many reports suggested he had simply licensed his name to the developers. But that too could play into a Democratic campaign to portray Trump more as a master of self promotion than a good businessman.

The city has not yet finished processing the DNC’s request, according to its public records site. Such requests often take weeks to fulfill.
