I’m guessing Roberts Rules stuff.
As a quick and dirty thing, you can call a voice vote of ayes and nays. If it’s not particularly close, it’ll be obvious what the outcome is, the Chair will call the result, and everyone moves on. However, any member can call bullshit on the Chair, and then it goes to a more formal process.
So without watching the whole damn video, it’s probably that the voice vote went one way, the Chair said it was the other, got called on it, and the roll call vote went against him.
This is a very common hypocrisy among first gen US immigrants. I’m a good Irish, not like those dirty ones coming over now; we should keep them out.
