The Minnesota Democratic-Farmer-Labor (DFL) Party announced on Tuesday that it’s planning to file a federal election complaint against Antone Melton-Meaux and the team of anonymous vendors assisting his bid against progressive freshman Rep. Ilhan Omar, citing reporting by Too Much Information (TMI).

As TMI reported last week, the Melton-Meaux campaign has routed most of its spending through three anonymous companies, at least two of which were incorporated in Delaware shortly before the payments started. The campaign’s payments to the firms accounted for 78 percent of its overall spending as of July 22, according to a TMI review.

The DFL complaint with the Federal Election Commission (FEC) alleges that the Melton-Meaux campaign’s maneuver is being used to evade longstanding laws requiring disclosure of how campaign money is being spent. The party accuses Melton-Meaux, his campaign and the companies of violating campaign finance laws by “conspiring to intentionally obscure the individuals providing services to Antone for Congress.”
