The tradition of using a Bible during the swearing-in goes back to the very first inauguration, but not all Presidents have used one.

President Donald Trump, when taking his most recent oath of office, did not appear to place his left hand on either of the Bibles brought to the swearing-in ceremony in the Capitol Rotunda on Monday.

The president-elect eschewed the star-spangled “Trump Bible” in favor of volumes with personal and national history.
