Navarro is correct. If the January 6 joint session of Congress lasts past January 20, then the inauguration is delayed until the joint joint session is complete and determines a winner of the electoral college. The joint session is likely to be delayed past January 6 due to multiple objections. Each objection requires two hours of floor debate. Plus there’s additional administrative time until the two houses convene for each two hour debate plus reconvene for the joint session after each two hour debate. That’s usually four hours from the time of the objection until the count continues after the debate.
There are fifty one slates of electors. There are five hundred and thirty eight electors. One Senator plus one Congressman can object to each of the fifty one slates. Or if they want to delay it even more they can individually object to each of the 538 electors. Requiring 2 hours of debate (about four hours of interruption) each time.
Congress also needs to sleep at night. It can easily go past January 20. And Michael Pence is the presiding officer of Congress who rules on how to handle each objection.
Freilichen Purim!
P.S. There’s a legitimate constitutional debate as to whether the Succession Act is constitutional in placing non-members of the Executive Branch (the Speaker of the House and the President Pro Temp of the Senate) in the line. The Attorney General has the authority to determine its constitutionality and how to carry out the law. If it seems likely they’ll be no declared winner from the joint session of Congress before January 6, the AG potentially could rule that the Speaker and Pro Temp are skipped and therefore Secretary of State Mike Pompeo becomes Acting President on January 20, until the joint session declares a winner.
Freilichen Shushan Purim!
