Hmmmm.... is right.
Excellent points.
Why hasn’t he fired the Parliamentarian?
Can POTUS direct him to do these things you’ve suggested?
POTUS does not need to direct him...
the Constitution has already given him that authority...
Over the decades that authority has been passed to a made up entity called majority leader (not capitalized on purpose) so the Vice President can just relax.
The only way out of this mess is the constitution, as written.
Enforce it!!
