"Biden is corrupt for what happened with his son Hunter and the Ukrainian prosecutor who was investigating him. "
There's a lot packed into that sentence which deserves picking out
Firstly, what Trump says he wants investigated is the allegation that Joe Biden threatened to withold money from Ukraine (he was vice president at the time) unless they removed the local prosecutor in a post-Yanukovich anti-corruption inquiry into the Yanukovich-era-founded Burisma energy holding company. Biden's son was on the board of that company. Biden claims the prosecutor's removal was because of corruption allegations against the prosecutor and that the load was questioned in relation to those allegations.
So the prosecutor was not investigating Hunter Biden firstly, rather the company, and second, the counter allegation is that the prosecutor was apparently scarcely less corrupt it seems than Burisma. Not an uncommon scenario in Ukraine.
The key point I think made by the Democrats is that Trump was putting pressure on Zelensky for his own domestic political reasons.
Which is, of course, in turn denied.
This is a space to be watched.
