I heard this mentioned somewhere and have been giving it some thought. IF it is now ok to impeach Trump as a citizen then surely that then opens the door for other previous presidents to be called to answer for their crimes committed whilst in high office? Would it be possible to do so for Obama, Bush and Clinton? Could they lose their SS detail and perks of their previous post?
When guilty of crimes against humanity, impeachment is a waste of time and resources. Military tribunals are worth their weight in gold.
