We long ago blew past any meaningful controls on political giving in American elections. Now we should focus on the rules governing political spending, which are in equally terrible shape. For that we can blame the Trump campaign and the federal government’s feeble enforcement efforts.

Anyone who has spent time reviewing Donald Trump’s campaign spending reports would quickly conclude they’re a governance nightmare. There is so little disclosure about what happened to the billions raised in 2020 and 2024 that donors (and maybe even the former president himself) can’t possibly know how it was spent.

Federal Election Commission campaign disclosure reports from 2020 show that much of the money donated to the Trump campaign went into a legal and financial black hole reportedly controlled by Trump family members and close associates. This year’s campaign disclosures are shaping up to be the same. Donors big and small give their hard-earned dollars to candidates with the expectation they will be spent on direct efforts to win votes. They deserve better.

During the 2020 election, almost $516 million of the over $780 million spent by the Trump campaign was directed to American Made Media Consultants, a Delaware-based private company created in 2018 that masked the identities of who ultimately received donor dollars, according to a complaint filed with the F.E.C. by the nonpartisan Campaign Legal Center. How A.M.M.C. spent the money was a mystery even to Mr. Trump’s campaign team, according to news reports shortly after the election.

All but 18 of the 150 largest expenditures on a Trump campaign’s 2020 F.E.C. report went to A.M.M.C. None of the expenses were itemized or otherwise explained aside from anodyne descriptions including “placed media,” “SMS advertising” and “online advertising.” F.E.C. rules require candidates to fully and accurately disclose the final recipients of their campaign disbursements, which is usually understood to include when payments are made through a vendor such as A.M.M.C. This disclosure is intended to assure donors their contributions are used for campaign expenses. Currently, neither voters nor law enforcement can know whether any laws were broken.

A.M.M.C.’s first president was reported to be Lara Trump, the wife of Mr. Trump’s son Eric. The New York Times reported that A.M.M.C. had a treasurer who was also the chief financial officer of Mr. Trump’s 2020 presidential campaign. Jared Kushner, Mr. Trump’s son-in-law, signed off on the plan to set up A.M.M.C., and one of Eric Trump’s deputies from the Trump Organization was involved in running it.
