The Campaign Legal Center cited recent reporting by The Associated Press and others in the complaint, which was filed with the Federal Election Commission. It alleges that the degree of coordination and communication between DeSantis’ campaign and Never Back Down, the super PAC supporting him, crossed a legal line set in place when the Supreme Court first opened the door over a decade ago to the unlimited raising and spending such groups are allowed to do.

Last week, the AP reported that multiple people familiar with DeSantis’ political network said that he and his wife had expressed concerns about the messaging of Never Back Down, the largest super PAC supporting the governor’s campaign.

The governor and his wife, Casey, who is widely considered his top political adviser, were especially frustrated after the group took down a television ad last month that criticized leading Republican rival Nikki Haley for allowing a Chinese manufacturer into South Carolina when she was governor.

DeSantis’ team shared those messaging concerns with members of Never Back Down’s board, which includes Florida-based members with close ties to the governor, according to multiple people briefed on the discussions. Some of the board members then relayed the DeSantis team’s wishes to super PAC staff, which was responsible for executing strategy, the people said.
