Now the Donald is almost certainly on the way out and as a consequence will loose his Presidential Immunity, what should happen next?

One article I've read is that Biden should give him a pardon to put a line under the last 4 years. As he'd the quietly fade into history...

Personally I think, if only to demonstrate that such actions have consequences and the whole "rule of law" thing there should be an investigation and charges at Federal level where appropriate along with the State charges.

Either way I imagine The Donald will start the election campaign for 2024 in February 2021 which is after all his favourite part of being president.

What do other think is going to happen?
