On the list of things that are important, anything having to do with Stormy Daniels is pretty low on the list, but that doesn’t mean her case can’t be pretty consequential. After all, former Trump bagman Michael Cohen was sentenced to three years in prison in part for his role in paying Daniels for her silence about an affair she had with Donald Trump. And, you might remember, President Trump was “individual-1” in that case. The only reason that Trump wasn’t convicted for the same crimes as Cohen is that there is a rule at the Department of Justice that precludes its prosecutors from charging a sitting president.

Nothing says Trump can’t, or shouldn’t, do jail time once he leaves office, so anything that bolsters his involvement in the Daniels case can weaken his future defense. And that’s what happened on Monday in a California Superior Court, where a judge ruled that Trump will have to pay for Daniels legal fees in a case related to her effort to escape a non-disclosure agreement.

Trump’s lawyers tried to argue that he wasn’t a party to the agreement, but the judge was having none of that for two reasons. First, he reimbursed Michael Cohen the $130,000 the non-disclosure cost, and second, the Trump legal team had previously attempted to force arbitration in a defamation suit that Daniels filed against him, per the terms of the non-disclosure agreement. Since he had both paid Daniels for her silence and argued in court that its terms should be enforced, the judge saw no reason to rule that Trump was not bound by the agreement himself.

This creates a predicate in court to argue that Trump was most definitely a witting participant in the conspiracy that landed Cohen in jail. I think that was already close to a slam-dunk case, but every little bit of legal scaffolding that is erected will help nail down a conviction, assuming anyone seeks one.

In the short term, the ruling will only cost Trump about $45,000. But it has the potential to do him more damage in the future. Paying off porn stars is hardly one of Trump’s biggest crimes, but there’s no reason he should escape the same justice Michael Cohen faced.
