Nice, he's giving the sleeves out of his vest.
I haven't heard of one government in the US even thinking about demanding proof of vaccination.
I'm thinking what are you saying????
Giving the sleeves out of his vest????
What does that mean?
Sorry. Old negotiation term.
It means offering up something that sounds significant but isn't really of value at all.
In this case, barring governments from requiring vaccine passports sounds good but I don't think any of them were even considering it.
