You mean the dirt about how Biden's son, Hunter, was taking millions from a Ukrainian oligarch and funneling it though banks in Latvia and Cyprus, with Democrats and their sycophantic pawns in the media telling us they didn't see a problem? Wasn't it dear old dad who threatened the Ukrainians if they didn't call off their investigation of his son, claiming the prosecutor was corrupt? Talk about irony!
Ultimately, the issue got dropped after the OMB director, Mick Mulvaney, removed his objection, so your claim of an official quid pro quo, i.e. that Zelenskyy would not get the weapons until after an investigation was conducted, is false.
Meanwhile, what did BOb and Sleepy send the Ukrainians? Apparently, they were supposed to throw radios at the Russians when they crossed the border.
