We can count statists like cdcox, KChiefer to justify this extravagance because Biden has a posse to bring along.
The question that should be asked here is regardless of party, why does the U.S. VP, have to travel anywhere in the first place?
He doesn't. He has no official functions that authorize such a trip. It's a do-less post and breaking ties in the Senate doesn't require it.
So it is PURE WASTE!
It doesn't stop the statists though.
