Presidents always say that. That does not mean a thing, Ike said "Nixon has done great things while I was in office" The Reporter asked "like what"? Ike said come back in a few days and ask again. I may have something.
Even Joe says she helped pass every major legislation and her staff is interlocked with his staff.
How much authority any VP has depends on the President they serve with and Joe has given Kamala a LOT of authority and she has fumbled the ball.
You have no idea how American politics work.
Kamala was sitting over the Senate, as all VPs do. In her case, she had a couple of votes, because they only vote to break a tie. The Senate was nearly equally split . That is unusual.
She had very little power. I see why you are wrong so often. You do not have a clue how our system works.
