And Trump will only have to take the oath once (upon the Bible), so that should save some time.
And for President Trump, ONCE IS ENOUGH; unlike BO’B who found a need to take the ‘oath’ twice in BOTH terms.
First inauguration day a secret oath (do over) done the second time.
Second inauguration day a secret oath the day BEFORE (a Sunday) the public oath. The lame excuse used is now forgotten. Rules must be different when the won is not a NBC.
