Don’t forget he doesn’t have two impeachments, two and counting indictments, additional federal investigations underway, penchant for persistently lying about things where lying isn’t even needed.
He can walk and talk just fine. Like everyone doesn’t trip. 
He doesn’t need help putting Trumpy in prison. Trumpy is doing that just fine on his own. But I haven’t seen where Biden is the one prosecuting or bringing charges against the Orange turd. Actually, no politician is. Maybe you can share a link to that. Oh you can’t. Because it isn’t political with Biden or anyone else doing this. It’s criminal and the idiot did it to himself. He fucked around. He’s about to find out.
There will likely be a third indictment from Georgia. They have to do it, because the heat is coming down on Biden. But for all of the indictments and impeachments, it's clear they are all partisan political tactics designed to get rid of Trump, because they are afraid they cannot beat him on the issues at the ballot box.
If you're saying Biden "can walk and talk just fine," you are either lying or just not paying attention.
You want a link about Biden's involvement in prosecuting Trump? Right here:
https://www.politico.com/news/2021/10/08/bannon-jan-6-subpoena-515681 Biden had to waive executive privilege, twice, for the DOJ to get the Trump subpoena. So yes, this is a Biden prosecution, signed off on by the Biden Attorney General. So we have the Biden Administration trying to lock up their chief political rival for life. Cuba would be proud.
