People voting for an elected official is different than that elected official breaking the law. People can't vote to break the law. They can vote to rewrite the law, sometimes, depending on how the law is written. Often in the US we vote for elected officials who write law and then the elected president who enforces the law.

So whether tens of millions of people voted for Trump doesn't mean Trump can just disregard law because people liked him and maybe even liked that he said he would disregard the law. As far as I know, that's not how the rule of law works in representative democracies.
