Pro-Trump super PAC files ethics complaint against potential 2024 opponent Ron DeSantis

Former President Donald Trump and his allies have ratcheted up their attacks on potential rival Florida Governor DeSantis, whom Trump acknowledged to reporters earlier this week is "probably" his biggest challenger in the presidential primary.

A Trump source familiar with pro-Trump super PAC MAGA Inc.'s plans tells CBS News that it has been extensively reviewing DeSantis' record as a Florida assistant U.S. attorney, congressman and governor. 

On Wednesday morning, MAGA Inc. filed a 15-page complaint with Florida's Commission on Ethics that claimed DeSantis is running a "shadow presidential campaign" that violates state and federal election law.
