Constitutional order of succession

[DouglasKC]

I thougt that was only for office of president, not vp. Pelosi doesn’t become vp if pence resigns.

[Republican Wildcat]

That only applies to President. A new Vice Presidential appointment would be voted on by both Houses of Congress.

With the office of the Senate President being vacant, the Senate President Pro Tempore would preside in his place.
