It will be nothing, it's a last ditch effort to get rid of Trump because they have absolutely no one that can win the presidency.
They wanted so bad for it to be some threatening phone call ordering a witch hunt on Biden. He says "Do us a favor", so what, he's form New York where that is a common phrase. And at no time are the conditions attached to it. The only thing I scowled at was him asking for his private attorney (Giuliani) to help in the investigation, but I don't see it as so wrong as to be impeachable.
