There were a couple of hearings going on which I think is what caused issues with a quorum because there often were not 51 Members in the chamber which allowed Republicans to question voting.

I think they need to have a quorum. Therefore if they are not there, there can be no votes. One party can try as hard as they want to drive things through, but they need a quorum. Therefore quorum calls and Sargent-at-arms. They need to have at least 51 senators present for a quorum. I don’t think they are allowed to vote without the quorum. So, no rubber stamping without a quorum.

Chaos in the Senate Yesterday

I think it’s a rubber stamp unless they have don’t have a quorum (not an expert, just spitballing here…)
