Yesterday's vote was due to a 'release the Epstein files amendment' that the Dems were able to add to the crypto bills. A "yay" on the procedural vote would have allowed not only debate on the crypto bills but also debate on the release of the Epstein files and who knows what else.
The "nay" vote prevented the Dems from hijacking the debate on the crypto bills. It was a procedural vote that the Dems caused by their amendment.
That's all this was, a minority party procedural move to try to prevent debate and passage, of a majority party bill.
