High crime and misdemeanors is the text that's used in the constitution but that doesn't necessarily exclude impeachment for something that isn't a crime. ...
I kind of think that "High

We can obviously debate all day on whether or not Trump 'should' be impeached, but It's pretty clear in the Constitution that congress doesn't have the power to charge someone with a crime, just remove them from office.
If they impeach someone in the Executive or Judiciary branch, that doesn't make that person a criminal. That doesn't make them a criminal or even prove they committed a crime.
