Anna Massoglia for Open Secrets:

Former President Donald Trump’s presidential campaign aides played key roles orchestrating a rally protesting certification of President-elect Joe Biden‘s victory in the 2020 presidential election before hundreds of rioters breached the U.S. Capitol on Jan. 6.  

But the full extent of the Trump campaign’s ties to the protests may not be not fully known due to its use of shell companies that hide details of its financial dealings and the central role “dark money” played in the protests.

Multiple individuals listed on the permit granted by the National Park Service worked for Trump’s presidential campaign, as first reported by the Associated Press over the weekend. That raises new questions about the Trump campaign’s lack of spending transparency and the unknown extent of the event’s ties to Trump aides.

Trump’s campaign disclosed paying more than $2.7 million to the individuals and firms behind the Jan. 6 rally. But FEC disclosures do not necessarily provide a complete picture of the campaign’s financial dealings since so much of its spending was routed through shell companies, making it difficult to know who the campaign paid and when.
