The premise for the impeachment starts out by saying that Trump’s claim of the election being stolen is false.
So now as a defendant in an impeachment trial Trump will have all the power he needs to compel evidence with discovery and prove his claim in a public forum.
That’s a good point. Republicans can cry about how 2nd Impeachment would divide the country, but it’s already divided. Let the Democrats make fools of themselves — and then be cross-examined. What would be especially telling if it comes out that the violent ones actually have AntiFa/BLM backgrounds.
