Trump wants to pay his immense legal fees with campaign donations. US law prohibits using campaign funds for personal expenses.
Trump has already been able to use donations to cover some of his legal fees on the grounds that his defense is campaign-related. However, it is not legally possible for Trump to use the donations directly to pay a fine or bail. Trump's campaign team wants to reallocate donations - and has invited people to a gala in Florida. There will be contributions from 20.24 to 3300 dollars. It is unclear whether the rezoning will work.
