Trump commited provable criminal offenses while in office, and yet more criminal offenses after his time in office.
Excuse from some Republicans who voted against his conviction in the second impeachment was that our legal system is perfectly capable in holding him accountable....well it turned out it wasn't and those ongoing criminal cases against Trump were halted for a very political reason of him winning an election.
Another excuse was that at the time of the impeachment Trump already left office so impeachment is moot.
Now all those excuses were conclusively proven false, so the case for impeachment could not be more clear.
