My question was more of a concern as to whether his role in presiding being taken over by the Chief Justice had any effect on him breaking ties. I do not believe it does, but not clear.
The narratives leading up to the impeachment circus has said the VP can break ties. I don’t know if that is limited to procedural issues but I assume he has the power as president of the senate still. The chief justice is presiding legally over the process, not as a member of the senate.
