I'm reading that J.D. Vance's reaction to Kamala Harris's swearing in of new Senators today has gone viral.

I don't understand why. It's an interesting situation, the defeated presidential candidate performing this role, but it is her duty as the current President of the Senate (i.e. Vice President), and J.D. Vance looks happy, but it's not as though he's taunting her. He's there, along with Ohio Gov. Mike DeWine, former U.S. Sen. Rob Portman of Cincinnati, to support the new Senator from Ohio, Bernie Moreno:

Some news media are calling attention to this other awkwardness: "Kamala Harris Heads to Capitol to Swear-In Senators Who Won’t Even Say Her Name Right" (Time), "Kamala Harris will give oath of office to GOP senators who couldn’t get her name right" (Independent).

It seems to me that this was a formal, required ritual, and everyone went through the motions with dignity and collegiality.
