Yeah, that could be garbage. Might not be, but could be.
Hey, I've got a great idea! How about if Trump just asks Zelensky politely to look into the whole thing a bit?
We'd get the straight story then.

Calling it the "Hunter Biden investigation" is the trash part. They probably did bribe the prosecutor to not investigate them.
We've already looked into it though.
Ukraine has already looked into it, at least twice by two different president/prosecutors.
Now, apparently Ukraine is looking into it again. If nothing comes back, will you believe we've got the story straight and nothing happened? I doubt it.
