According to a couple of the accounts I've read about the 2020 election and the last days of the trump administration, Biden and Graham were actually fairly close friends. There's a video somewhere of an interview with Graham in which he actually starts to get genuinely emotional when the subject of Beau Biden's death came up.
It all came to a crashing halt when Graham drank the Hunter Biden Flavor-Aid*. Graham said something about Hunter Biden's "wrongdoing" to Biden over the phone, and that was the end of it.
That said, one can see the beginnings of the madness whenever Democrats on the Judiciary Committee brought up genuine concerns about one of trump's SCOTUS nominees. Graham seemed genuinely angry that someone would do such a thing, no matter how credible the accusations.
The Graham I saw in that interview showed a certain amount of humanity. Patrician right-wing humanity, but humanity nonetheless. I keep hoping that Data will show up and flash lights in the eyes of Graham and the rest of the trump-addicted Enterprise D crew. Of course, it may be too late for that.
And for those who don't get the allusion - here's a clip from the Star Trek TNG episode in question. An alien creates what looks like a video game intended to develop an addiction to whoever plays it. The alien then plans to control the Enterprise once the whole crew is hooked. Everyone gets addicted except Wesley Crusher and Data, who figures out a way to circumvent the plot. The episode also includes a very young Ashley Judd.

*Fun fact - during the mass murder-suicide at Jonestown, in Guyana, in 1978, the cyanide was mixed not with Kool-Aid, but with Flavor-Aid. It should be "drink the Flavor-Aid," not "drink the Kool-Aid." Look it up if you don't believe me.
