Trump cannot pardon himself or the conspirators who aided

 I believe it is incorrect that Trump can pardon anyone. The Constitution says he can "Except in cases of impeachment". Presumably impeachment follows high crimes and misdemeanors. If the high crime is a conspiracy than all members of the conspiracy cannot be pardoned, they are tied into the "impeachment" by way of conspiracy. All the campaign 'conspirators' and the President himself have committed treason, which I'll assert follows their conspiring to aide Russia in interfering with America's internal affairs, particularly the election of 2016. They are all traitors conspiring with the impeachable President to commit treason against the United states. I believe this is correct and easily seen. Any prosecutor and judge would probably accept the premise and argument.
