Smith offered another example. “Go back to 1999. Hillary Clinton buys a house in New York. She bought it clearly to influence the election — I mean absolutely, right? — because she had to have a residence in New York. It is totally indisputable — that is a reason why she bought it. But it’s not a campaign expenditure. It doesn’t matter. People buy houses. We would have wanted to inform the jury about the notion of personal use and talked about the idea that what is a campaign expense is an objective test, not a subjective test.”

When it comes to the details of the Trump prosecution, knowing how campaign finance law works has led Smith to believe that what is alleged to be the core violation in the case, that paying Daniels amounted to a campaign contribution or a campaign expenditure, is simply not true. “I can tell you my personal belief is that clearly paying hush money, or paying for a nondisclosure agreement, does not constitute a campaign expense,” Smith said.
