To gain the presidency it is all-but-mandatory to have the enthusiastic backing of a big chunk of voters and the tacit or explicit approval of around half of them. Combine mass popular support with executive power and there isn't a lot practically that can be done.
Furthermore it appears that most of the US politicians have some sort of borderline-corrupt activity going on if not being actively involved in something illegal (Epstein springs to mind, various scandals that turn up around presidential elections). People in glass houses are cautious in their stone throwing.
And a final and decisive stroke - there is plausible uncertainty about whether the action is illegal. These are people who write the law, they are not expected to be stay-inside-the-legal-lines types because they all have different opinions on where the lines should be and are usually in the process of drawing them. They appoint the people who determine what the words mean and that leads to occasional creative reinterpretations. There isn't time to prosecute over every detail that someone objects to given the range of objections there are.
