Impeachment for Insurrection: The Second Trial of Donald J. Trump. A reposting
An impeachment is not the same as a criminal trial, which may be what Donald Trump is facing, given that the January 6 Committee has referred four possible crimes to the Justice Department.
Trump had TWO impeachment trials, the first for holding up congressionally approved arms shipments to Ukraine until they opened an investigation of his opponent, the second for the insurrection on January 6. This podcast addresses the second trial.
There is also an earlier podcast on The Logic of Impeachment, focusing on that earlier situation.
If you don't remember that event this may help clarify some of the issues.
