Here's a possible answer. It might be a timing issue.
>>>Ciara Torres-Spelliscy, a professor at Stetson University College of Law in Florida, said the risk of paying defense attorneys with contributions is that the FEC or the Justice Department may later decide that it was an illegal personal use of campaign funds. She doubted such a case would be brought against Trump now because doing so might slow the ongoing federal prosecutions overseen by Justice Department Special Counsel Jack Smith.
“But after the Mar-a-Lago and January 6th cases are done, I would not be surprised to see a personal use case against Trump for using these millions in donations that are meant to go to his political campaign going instead for the personal use of keeping him out of prison,” Torres-Spelliscy said.<<<

Trump's legal problems might get significantly worse before too long.
