To me, the serious issue is Biden's leveraging of US aid to force the firing of an official in another country's government, for ANY reason. The moron has openly admitted to doing that. That's conclusive and can't be characterized as anything but abuse of power.
The mass media has a narrative for that (they always do :-) ).
Joe was just making an idle boast, the entire international community actually wanted the guy fired, bla, bla, bla....
You know Joe, he says such dumb stuff... :-)
