Lindsey Graham's smackdown was almost note for note parallel to Joseph Welch (Chief counsel for US Army) taking Joe McCarthy to task during hearings on communist infiltration in the 1950s. McCarthy sandbagged him with accusations against a man he'd put forth himself, a protege of sorts. Welch didn't like that one bit and he showed his contempt for McCarthy. The democrats hailed him as a hero then and to this day. That was their jumping off point to ruin McCarthy. "It's not about protecting commies, it's about taking down a shameful man with no decency or decorum!"
Welch accused McCarthy of having no sense of decency, of smearing an innocent young man, and then refused to discuss it further because he said McCarthy had been with him several times and never brought this up, saving it for a public hearing.
Graham did all the same things, albeit a bit more forecefully. Why doesn't the left hail him a hero too?
