Almost every single US president has broken the law.
Maybe they should stop doing that quite so much? Surely they have really good lawyers to help advise them on how to not break the law while in office.
Not every violation law also violates the Fourteenth Amendment.
Political opponents could avoid persecution (prosecution?) by not breaking the law or violating their oath. But once the precedent has been sent, given the way US politics has turned into trench warfare, future politicians will decide that this is a really handy way to remove someone they can't remove at the ballot box.
