He has the absolute authority to take up a vote to any objections BEFORE the certification.
You seem to be confused about this
@libertybele. The states certify their results in the period between the general election and the meeting of the electoral college; the certification is intended to inform the electors. In the event of a controversy or challenge within the state the "safe harbor deadline" holds that if the challenge is resolved according to that state's laws no less than six days before the meeting of the electoral college then the resolved results are conclusive and Congress must accept the state's EVs. In the recent election all states had certified their results by December 11, and the electoral college met December 14; only Wisconsin failed to meet the "safe harbor deadline" for the recent election.
The statute you cited regulates how the certified EVs are counted during a joint session of Congress on January 6. Congress has no authority to object in any way to EVs at any point before they are opened and counted on January 6, nor is there any opportunity to entertain such an objection. In fact all the results are certified *before* any EVs are even cast. And the objection procedure you highlighted is now supposed to be only for EVs which do not benefit from the safe harbor deadline. The EVs of both AZ and PA were protected by the safe harbor deadline so even had Congress not recognized them that act probably would have failed to stand up at SCOTUS.
Look, I'm convinced the Ds cheated and will do so anytime they can get away with it. I don't think we know who truly won the last election because I have no confidence that fair results were certified in several states.
But they were certified and that fact removes all authority for anyone to do anything other than carry out the objection procedure you cited. And that procedure
was carried out even though it probably should not have been because both AZ and PA were within the safe harbor.
I would like to believe that a legal result is always a true and fair result.
But it isn't. And perversely insisting that we can perfect the law by reading our own preferences into it, like pretending that Mike Pence shirked authority and is now a coward and traitor, is the exact sort of lying that we criticize liberal judges for doing.
