Freedom 250’s corporate sponsors may have violated the Lobbying Disclosure Act.Some of America’s biggest corporations shelled out millions of dollars to support Freedom 250, the Trump administration’s public-private partnership that oversaw spending for the country’s semiquincentennial celebration.It was no secret who was involved: The Freedom 250 website proudly displayed nearly two dozen of its sponsors, including Palantir, Boeing, ExxonMobil, United Health Group, and more.But most of those corporations—including the defense contractors Lockheed Martin, GE Aerospace, and Northrop Grumman—did not disclose the payments on lobbyist contribution reports that were due to Congress by last Friday, according to a NOTUS investigation.Just three Freedom 250 backers made note of their event contributions in their recent filings, as required by the federal Lobbying Disclosure Act: Chevron, United Airlines, and RTX, according to NOTUS.The law “is certainly not airtight, and certain entities have found ways to try to exploit this law,” Aaron Scherb, a longtime ethics and democracy advocate, told NOTUS.“Nonetheless, it requires full disclosure of political spending when companies are trying to curry favor with an administration and elected officials,” Scherb said. “So, companies contributing to Freedom 250 should absolutely be required to disclose their political spending.”Freedom 250 is a subsidiary of Task Force 250, an entity that Donald Trump signed into existence by executive order days into his second term. It largely replaced the “America250” nonprofit that was created by Congress a decade ago to oversee the semiquincentennial’s funding and development strategies. Unlike America250, Freedom 250 is technically a limited liability company housed within the National Park Service’s charity arm, the National Park Foundation.Trump himself is the chair of Freedom 250, while the rest of his Cabinet are listed as members.“When it comes to other nonprofits, the question is always whether it was created and controlled by Trump,” Craig Holman, a government affairs lobbyist at the left-leaning nonprofit watchdog Public Citizen, told NOTUS. “But there is little question about Freedom 250.”
