You know the keep bring up the Bidens as a distraction on Trump's impeachment trial.
All kind of silly really, if Biden has done some thing wrong and they have evidence. Just hand it over to the authorities and let them investigate, surely POTUS has the authority to do that.
But it's a separate issue to the Trump impeachment trial, the evidence is clear that Trump is guilty, no ifs or buts.
It will be interesting to see if the republican senators uphold their oath and find him guilty, if they do I still think they will not vote to remove him from office. If they don't find him guilty it will set a precedent that future presidents can abuse their power in office
