If one is guilty the other is too.

No, it was Biden.

Biden is full of shit. He thinks he did something. Meanwhile the proof is right there about Trump. Either they both are guilty or neither of them are. Take your pick.

What your links didn't tell you is that Trump didn't tell Ukraine that the aid was frozen until several months has past. And Trump didn't bring it up as a threat link to Ukraine doing what he wanted, and the actual favor mentioned was looking into election interference in 2016 and Crowdstrike.
