I think Graham is doing everything possible to avoid bringing Joe Biden or his son into the impeachment process. Without either and their conduct/accomplishments explained in person, there is no impeachment.
I actually like this because it helps with the main goal. Shut this BS down and go home. I don’t trust Linda and I think he has Ukraine dirt on him too. So I don’t really expect him to go after Hunter but the big thing here is to shut down this rat Sh*t circus ASAP.
Remember how Graham promised to get to the bottom of the Kavanaugh smear with Judiciary hearings. Graham is a DS fifth columnist, he will never call his friend Biden or his disgusting spawn for hearings. Graham knows he is vulnerable to having his past Ukrainian shady dealings uncovered.
If Graham gets the Bidens in then it will be hard to keep Bolton and others out.
