Has Rudy even hinted that he's found evidence against Graham?
That said, I still don't trust Graham, and he does appear to be acting weaselly.
Whatever occurred in the Ukraine should be investigated thoroughly to prosecute criminal acts and prevent it from happening again.
If Graham or any other republicrat was involved in this then so be it. Period. I don’t think any of us doubt that many republicrats had their hand in the cookie jar, but I have not heard any allegations against Graham. Based on this, that means it is likely that there is no corruption by him given his position of responsibility in all of this and the thorough knowledge of Soros of the road map of corruption there.
The impeachment is part and parcel of the pro-active defense against the Ukrainian corruption involving Biden and many others. We can therefore safely assume that if Graham was involved it would have come out as that seems to be their playbook.
