The answer is tricky, according to legal experts. Generally, politicians cannot spend campaign money on legal expenses unless they are tied to a campaign, but many of the investigations involving Trump relate to his conduct as president and as a political candidate.

However, leadership PACs such as Save America also are not allowed to directly support their own candidate's campaign. Richard Briffault, a professor at Columbia Law School and an expert on campaign finance issues who has supported Democratic candidates, said that because Trump is fighting criminal charges during a presidential campaign, it is possible that covering legal fees could be considered a benefit to his campaign.
