>before and after it was clear that he put bounties on American soldiers.
There is no proof Russia actually put bounties on soliders.
>Calling Americans soldiers losers and suckers.
No proof he did this except for McCain. Wouldn't be treason if it were true.
>Pardoning war criminals.
If this is the same case I know about then he was acquitted of war crimes. I doubt it would be treason though.
>Telling voters to commit election fraud by voting twice.
Maybe but I think he was trying to call out the risk on mail in voting. Most of media was not talking about the risks like people double voting. After his statement they talked about it. I think that was his point.
>And, last but not least, killing more than 200k Americans even though he knew perfectly of coronavirus risks.
Not treason and Trump is not really responsible for all deaths. Trump does not have the authority to do what people want him to do. That is on the states. If Trump locked down the states which would have been unconstitutional he would have been called an authoritarian.
