More: The four companies each committed millions of dollars to the project through legal settlements with Trump in the months after the 2024 presidential election, seeking to resolve claims they had harmed him by restricting his access to social media or defaming him in their coverage. The commitments totaled at least $63 million, according to company statements and media reports.

But the Donald J. Trump Presidential Library Fund, Inc., which was set to receive at least some of the settlement funding, was administratively dissolved last September by Florida officials after it did not submit a mandatory annual report. Three months later, Jacob Roth, the lawyer who originally incorporated the fund, filed articles of dissolution, OpenSecrets first reported last year.

"Now it is unclear where this money has gone, exacerbating concerns about corruption that were apparent at the time of the settlement," the lawmakers wrote.
