GOP will never stop investigating, despite lack of evidence (eg Bengahhhhhzi,) that's why I don't understand Ds rush to end the Ukraine hearings and rush to a Senate trial which will go nowhere when there are soooo many credible leads to follow.
End it early, Trump will just say he's acquitted, lie about what they found, and the country will move on, just like after Muller laid an egg.
No consequences, no deterrence, he'll just be up to more scams.
Honestly, just keep this open, follow the evidence, and if it has to run past the election, then so be it.
