Interesting. Thanks. I suppose for national security, there must be some degree of CIC overlap.
I think really it happened the way it did for Zero’s second Innaugural because, per the Constitution it must occur at noon on the 20th, but the twentieth was a Sunday and the big public event was planned for Monday the 21st. I suppose this could only occur when an incumbent is re-elected. I don’t think that Trump could get sworn in early while there is another standing President.
