How to Impeach is an ouline of the method of conducting an impeachment.
Impeachment itself is technically just an accusation of guilt, made by the House of Representatives. As we saw during the Clinton years a President can be impeached without being removed from office if the Senate did not Convict. In this case, unlike the Clinton case, there are clear high crimes and misdemeanors which ought to be addressed.
Local governments can play a role in impeachment. While they cannot directly impeach a President but when local governments pass Impeachment resolutions it puts pressure on Congress to do the same.
Proposed Resolutions for Impeachment by Cities, Counties, State Legislatures or Political Party Committees is several ways to word such a local Impeachment Resolution.
